Why Is My Stomach Pain Not Going Away?

Many people in Hyderabad come to me and say exactly this: “Doctor, all my tests are normal, but my stomach pain is still there. Is it only in my mind?” And honestly I hear this every single week. From software engineers in Madhapur who sit ten hours at a desk. From teenagers in coaching centres in Ameerpet who skip breakfast and survive on tea and biscuits. From homemakers who have been managing three things at once for years. From elderly patients who drove forty minutes across Banjara Hills on potholed roads arriving with pain that nobody has been able to explain.

The pain is not in your mind. And the dismissal “your reports are normal, you are fine” is one of the most damaging things a patient can hear. It does not erase the pain. It erases the person.

At IBAP Clinics, my approach is clear. First believe your pain. Second understand where it is actually coming from. Third use targeted, safe, interventional techniques to address that source directly when routine medications have run out of answers.

🎯 Dr. Vijay’s Analogy

Think of it like this. If your abdominal pain has become an unwanted tenant in your house, I am not handing you earplugs in the form of painkillers. I want to find exactly where that tenant is hiding organ, nerve, muscle wall, or brain-gut axis and, scientifically and gently, ask him to leave. Each hiding place needs a completely different eviction notice.

IBAP’s COMPREHENESIVE TREATMENT SERVICES

🔑 The Core Principle

Chronic abdominal pain lasting more than three to six months that has failed to respond to standard treatment is not a dead end. It is the beginning of a more precise diagnostic process. The key question is always: visceral organ? Abdominal wall? Functional gut-brain axis? Neuropathic nerve injury? The answer determines everything that follows.

A Clinical Taxonomy of Chronic Abdominal Pain

Before any treatment can be planned, the pain must be classified. This is the foundation of the interventional pain approach and the step most often skipped in general medical settings. There are four distinct categories, and they require entirely different treatments.

Visceral / Organ-based

Chronic pancreatitis
Pancreatic cancer
Cholecystitis / biliary
IBD / Crohn’s
Mesenteric ischaemia
Gastric / hepatic cancer

Abdominal Wall (CAWP)

ACNES
Myofascial pain
Post-surgical nerve injury
Scar / adhesion neuralgia
Hernia-related pain
Intercostal neuralgia

Functional / DGBI

IBS
Functional dyspepsia
CAPS
Visceral hyperalgesia
Gut-brain axis pain
Narcotic bowel syndrome

Neuropathic / Referred

Post-herpetic neuralgia
Thoracic radiculopathy
Post-surgical nerve injury
Diabetic neuropathy
Intercostal neuralgia
Spinal referred pain

Category 1: Visceral / Organ-based Pain

This is pain arising from internal organs the pancreas, stomach, liver, biliary system, intestines, or malignancy. The character is typically deep, dull, and cramping; poorly localised; often referred to the back; worsened or triggered by food. It may come with nausea, vomiting, weight loss, or change in bowel habit. The pain signals travel through the splanchnic nerves and the coeliac plexus which makes these nerve networks the primary interventional targets.

Category 2: Abdominal Wall Pain (CAWP / ACNES)

This is perhaps the most frequently missed diagnosis in all of abdominal pain medicine. Anterior Cutaneous Nerve Entrapment Syndrome ACNES occurs when the small sensory branches of the thoracic intercostal nerves become trapped as they pierce the rectus abdominis muscle. The pain is sharp, well-localised the patient can point with one finger worsened by movement and muscle tensing, and entirely unrelated to eating or bowel function.

This pain does not show up on a CT scan. It does not appear in blood tests. But it is real, it is common, and it responds beautifully to a simple injection. The diagnosis requires one bedside manoeuvre the Carnett sign.

Category 3: Functional / Gut-Brain Axis Pain (DGBI)

When all scans, endoscopies, and blood tests come back entirely normal yet the pain is real, frequent, and ruining daily life we are often dealing with a disorder of gut-brain interaction (DGBI). The nervous system has become over-sensitised. Normal things digestion, mild gas, the usual stretching of the bowel after a meal suddenly feel like severe pain. The wiring is amplifying signals that should be silent.

In Hyderabad today, I see this pattern constantly. Teenagers under relentless exam pressure presenting with IBS-like abdominal pain. Software employees working twelve-hour days, eating at odd hours, ordering in at midnight. The gut-brain axis responds to stress like a loudspeaker with feedback it amplifies. It does not invent the sound. It just makes it unbearably loud.

⚠ Diagnostic Pearl: Narcotic Bowel Syndrome

Always screen patients who have been on chronic opioids for “undiagnosed” abdominal pain. Paradoxically, long-term opioid use can actually worsen abdominal pain through opioid-induced gut hypersensitivity. The patient and prescribing doctor both assume more opioid means less pain. In fact, the opioid is the cause. Recognition is critical treatment involves carefully tapering the opioid, the opposite of the usual instinct.

Category 4: Neuropathic and Referred Pain

Sometimes the pain in the front of the abdomen is coming from the back. A thoracic disc prolapse, a compressed nerve root at T7 to T12, post-herpetic neuralgia after shingles all of these can cause burning, electric-shock sensations, or crawling paraesthesiae in the abdominal wall that are entirely unrelated to any abdominal organ. The source is the spine; the symptom is in the tummy. Patients describe it as “ants crawling under the skin” or “a hot wire.” Missing this leads to years of unnecessary gastroenterological investigation.

Why Chronic Abdominal Pain Is Rising in India — My Honest View

I do not think this is only about biology. What I see in Hyderabad clinics every week tells a social story as much as a medical one.

Teenagers are arriving with abdominal pain driven by the pressure of school ranks, board results, entrance exams. They eat irregularly skipping breakfast, surviving on biscuits and tea during coaching hours, then eating heavily at night. Sleep is disrupted by screens, anxiety, and social media comparison. The gut-brain axis in an adolescent is extraordinarily sensitive, and we are stressing it systematically.

Software employees sit for ten to twelve hours with multiple monitors, driven by deadlines and review cycles. They eat at odd times Swiggy at 11pm, coffee as breakfast. The spine takes a beating from poor chair ergonomics and no movement. Then the evening commute on Hyderabad roads potholes, speed breakers, aggressive lane changes jars the spine further. Poor sleeping posture at home completes the picture.

Middle-aged and elderly patients have a different pattern. Long drives to temples, movies, social gatherings wonderful activities, but often on bad roads, in poor posture, for long durations. The result: spinal nerve irritation that presents as abdominal pain, or genuine visceral pain that has been dismissed too long because “at your age, some pain is normal.” It is not normal. And it is not acceptable.

Homemakers are perhaps the most overlooked. Continuous multitasking, irregular meals, delayed medical attention because the family’s appointments always come first. I have seen women who have had abdominal pain for three years and never prioritised getting it assessed properly.

Pain is not only from organs. It is from lifestyle, stress, posture, sleep, irregular food, and very importantly from the absence of empathy. When a doctor or family member says “all your tests are normal, you are fine,” it does not reassure the patient. It erases them. And erased patients delay care, escalate anxiety, and ultimately present later with more complex problems.

The Carnett Sign — 30 Seconds That Can Change Everything

First described by John Berton Carnett in 1926, this test has stood for a century. And yet I find it is almost never performed in general practice or gastroenterology settings. Patients arrive at my clinic having had three CT scans, an MRI, a colonoscopy, and a gastroscopy. Nobody has done Carnett’s test. It takes thirty seconds.

🧪 Performing the Carnett Sign — Step by Step

With the patient supine and relaxed, identify the point of maximum tenderness by deep palpation. Note this exact spot.
Maintain firm fingertip pressure at that point without moving.
Ask the patient to either: (a) fold arms across the chest and lift the head and shoulders off the table, OR (b) raise both legs straight off the table both options tense the rectus abdominis.
Positive Carnett — pain stays or worsens: The tensed muscle compresses the trapped nerve. Source is the abdominal wall. Treat the wall, not the organ.
Negative Carnett — pain eases or disappears: The tensed wall lifts away from underlying organs, shielding them. Source is visceral. Investigate internally.

An additional clinical pearl: abdominal wall pain patients can usually point to their pain with one finger — a small, finger-tip-sized spot. Visceral pain patients sweep their hand across a wide area. That one observation, before you even do Carnett’s test, is already telling you where to look.

Red Flags — When to Act Immediately

Before any pain clinic pathway is planned, red flags must be excluded. These features indicate a potentially serious underlying pathology requiring urgent specialist assessment, not just pain management.

🚨 Red Flags — Refer Urgently to Gastroenterology / Surgery

Unintentional weight loss of more than 5–10% body weight over 3–6 months
Fever with abdominal pain — suggests infection, abscess, or inflammatory disease
Blood in stool (red or black/tarry) or haematemesis (vomiting blood)
Jaundice — yellow eyes or skin, dark urine, pale stools
Severe pain that wakes the patient from sleep at night
Palpable abdominal mass or organomegaly on examination
New onset of pain in patients over 50 with no prior abdominal history

At IBAP Clinics, if any red flag is present on assessment, we coordinate immediately with gastroenterology or surgery colleagues. Your safety always comes before any interventional procedure.

What We Assess at IBAP Clinics

When you visit us, the first consultation takes thirty to forty-five minutes. This is not bureaucracy — it is the diagnostic work without which no safe intervention can be planned.

Detailed history

When did pain start, how does it feel cramping, burning, stabbing, dull. What triggers it: food, stress, movement, posture, long sitting, driving on bumpy roads. Relationship to motions, urination, menstrual cycle. Sleep pattern, occupation, and lifestyle.

Medicine review — including opioid screening

We carefully review all current and prior medications, especially long-term painkillers, NSAIDs, and opioids. Narcotic bowel syndrome must be actively excluded in anyone on chronic opioids for “undiagnosed” abdominal pain.

Structured physical examination

Systematic abdominal palpation to identify point of maximum tenderness, organ size, and guarding. The Carnett sign is performed on every patient with chronic abdominal pain. Spine examination where neuropathic referred pain is suspected.

Red flag screen

Weight loss, fever, blood in stool, jaundice, night pain, palpable mass — any positive finding triggers immediate coordination with gastroenterology or surgery before any pain intervention is considered.

Review of all prior investigations

We review every existing ultrasound, CT, MRI, endoscopy, colonoscopy, and blood result. We do not repeat investigations unnecessarily. But we look at them differently — through the lens of pain pathways, not just organ pathology.

Multidisciplinary coordination

Where needed, we align closely with the patient’s gastroenterologist to ensure no occult pathology SIBO, low-grade IBD, microbiome dysbiosis is missed before proceeding to interventional management.

Interventional Treatments — The Full Toolkit

Interventional pain management for chronic abdominal pain is precisely matched to the category of pain identified during assessment. What works beautifully for visceral pancreatic pain does nothing for abdominal wall nerve entrapment and vice versa.

4.1 — Abdominal Wall Injections (ACNES and Myofascial Pain)

When Carnett’s sign is positive when the pain is small, finger-pointable, worsened by movement, with normal imaging the abdominal wall is the target.

Trigger Point Injection

Local anaesthetic sometimes with steroid injected directly into the most painful spot. Often gives immediate relief within minutes. Confirms diagnosis if pain improves by more than 50%. Can be repeated for sustained benefit.

TAP Block (Transversus Abdominis Plane)

Under ultrasound guidance, local anaesthetic is deposited in the fascial plane between the internal oblique and transversus abdominis. Captures lateral cutaneous branches of T10–L1. Excellent for ACNES, post-surgical pain, and diffuse wall pain.

Rectus Sheath Block

Injection beneath the posterior rectus sheath bilaterally, capturing the anterior cutaneous branches of T9–T11. Ideal for midline abdominal wall pain and post-laparotomy pain.

Subcostal / OSTAP Block

Extended coverage of the upper abdominal wall T6–T10, capturing epigastric and subcostal pain. Useful post-upper laparotomy and for epigastric CAWP.

Iliohypogastric / Ilioinguinal Block

Targets IH and II nerves at the ASIS for lower abdominal wall pain, inguinal pain, and post-herniorrhaphy neuralgia. RF ablation of these nerves gives months of extended benefit.

Pulsed RF — Anterior Cutaneous Nerve

For recurrent ACNES where trigger point injections wear off quickly. Pulsed radiofrequency neuromodulatory rather than destructive applied to the identified cutaneous nerve.

4.2 — Sympathetic and Plexus Blocks (Visceral Organ Pain)

For deep visceral pain from chronic pancreatitis, malignancy, or severe gut pain, the target is the sympathetic nervous system specifically the plexuses and ganglia that relay pain signals from the internal organs.

Coeliac Plexus Block

Local anaesthetic with steroid injected around the coeliac plexus at L1 anterior to the aorta. The grand central station of upper abdominal pain. Best for chronic pancreatitis and non-malignant upper visceral pain. Provides weeks to months of relief; repeatable.

Coeliac Plexus Neurolysis

Absolute alcohol (50–100%) or phenol permanently destroys coeliac plexus nerve fibres. The gold standard for pancreatic cancer pain — 70–90% response rate. Can be done posterior (CT/fluoroscopy) or anterior (EUS-guided). Should be offered early, not as a last resort.

Splanchnic Nerve Block

Local anaesthetic injection at the splanchnic nerves at T11–T12. Offers broader coverage than coeliac plexus alone. Used as diagnostic confirmation before RF ablation — 80% temporary relief predicts a good RFA outcome.

Splanchnic Nerve RF Ablation

Radiofrequency heat (80°C, 90 seconds) applied to the bilateral splanchnic nerves at T11 under fluoroscopic guidance. Provides 6–12 months of meaningful relief. Significantly reduces opioid requirements. Repeatable when pain returns.

Superior Hypogastric Plexus Block

Targets the sympathetic relay for lower abdominal and pelvic visceral pain at L5–S1. Useful for lower abdominal malignancy, bladder pain, and some pelvic cancer pain. Neurolysis option available.

Lumbar Epidural / Infusion

Continuous epidural infusion of dilute bupivacaine at L1–L2 for acute-on-chronic pancreatitis flares. Provides analgesia, sympatholysis, may improve mesenteric blood flow and reduce ductal spasm. Underused for this indication.

4.3 — Spinal Cord Stimulation (SCS): When Everything Else Has Failed

For a carefully selected subgroup of patients with refractory visceral abdominal pain where organ-directed treatments, nerve blocks, and all medications have provided insufficient relief spinal cord stimulation offers a transformative option. A thin electrode is placed near the dorsal spinal cord through a needle, typically at the thoracic level. A small implanted device sends gentle, programmable electrical impulses that modify how pain signals are processed.

Think of it as a volume controller on the pain pathway. The underlying signal may still exist but the brain stops receiving it at the volume that was making life impossible. Multiple studies show improvement in pain scores, functional capacity, and reduction in opioid use for chronic visceral pain. And critically we always do a trial first. A temporary electrode for five to seven days. Only if the trial is successful do we plan permanent implantation.

4.4 — Intrathecal Drug Delivery (IDDS): For Advanced Cancer Pain

In patients with severe cancer-related abdominal pain where oral opioids provide inadequate relief or cause intolerable side effects severe constipation, drowsiness, cognitive impairment intrathecal drug delivery is a highly effective option. A small programmable pump delivers tiny doses of opioid directly into the cerebrospinal fluid near the spinal cord. Because the drug is delivered so close to its site of action, the effective dose is typically one-three hundredth of the oral dose. Dramatically less side-effect burden. Dramatically better relief. Always planned in close collaboration with oncology and palliative care teams.

Functional Pain, Stress, and the Indian Lifestyle — A Multimodal Approach

For functional abdominal pain, IBS, and disorders of gut-brain interaction, tablets and nerve blocks alone are not sufficient. Research is increasingly clear that combining medical treatment with psychological and lifestyle approaches gives substantially better long-term results. I always tell my patients: “Your pain is real. But your nervous system is trainable.”

Regular meal timing: Irregular eating is one of the most powerful triggers for functional gut pain. Three structured meals, no long gaps, adequate breakfast not biscuits and tea makes a measurable difference.
Sleep hygiene: Screen-free wind-down time. The gut-brain axis is profoundly disrupted by poor sleep. For teenagers especially no mobile phones after 10pm is not a lifestyle choice, it is a clinical recommendation.
Gentle exercise and yoga: Core strengthening, gentle stretches, walking. Not aggressive gym work. Sitting less is itself therapeutic.
Pain psychology and CBT: Cognitive Behavioural Therapy has the strongest evidence base for functional gut disorders. Gut-directed hypnotherapy and mindfulness also have supportive trial data.
Low-FODMAP dietary guidance: For IBS-type symptoms, dietary modification under dietitian supervision not self-imposed restriction can dramatically reduce symptom burden.
Stress management: Practical, structured techniques not advice to “just relax.” That is as useful as telling someone with a broken leg to “just walk.”

Comprehensive history, physical examination including Carnett’s test, red flag screen, review of all investigations. At the end of this consultation, you will have a clear classification of your pain and a proposed plan.

Specialist coordination if needed

Where red flags are present or occult pathology is possible, we coordinate immediately with gastroenterology or surgery colleagues before any pain procedure is planned.

Procedure day (day procedure, fasting required)

Most blocks are day procedures under ultrasound or X-ray guidance. You come fasting for four hours, we do the procedure, you stay for one to two hours for observation, and you go home the same day with written instructions.

Follow-up and response assessment

At two to four weeks and at three months, we assess degree and duration of pain relief, functional improvement, and medication reduction. Further sessions, SCS trial, or adjunctive functional pain strategies are planned based on response.

💡 Dr.Vijay’s Clinical Philosophy

Understanding and empathy are not soft skills in pain medicine. They are active components of treatment. The science is unambiguous: a compassionate consultation improves pain outcomes, reduces anxiety, and enhances the response to interventional procedures. When I tell a patient “I believe you, and there are things we can do” — that is not just kindness. It is clinical practice. I have seen patients cry in the consultation room — not from pain, but from the relief of finally being believed. That moment matters. And it is the foundation of everything that follows.

Some quick information

Why is my abdominal pain not going away despite normal tests and scans?

Normal investigations do not mean no pain. Chronic abdominal pain can arise from the abdominal wall (nerve entrapment that does not show on imaging), the gut-brain axis (visceral hyperalgesia that does not show on endoscopy), neuropathic nerve injury from the thoracic spine, or deeper organ changes that standard imaging misses at early stages. An interventional pain assessment including the Carnett sign bedside test and targeted diagnostic nerve blocks can identify the true source and guide a precise treatment plan.

What is ACNES and how is abdominal wall nerve entrapment treated?

Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is a frequently missed condition where small sensory nerves become trapped as they pierce the rectus abdominis muscle. The pain is sharp, localised to a small area at the lateral rectus edge, finger-pointable, worsened by movement and muscle tensing, and positive on Carnett’s test. It is treated initially with a trigger point injection of local anaesthetic and steroid often giving dramatic immediate relief. For recurrent cases, radiofrequency ablation or pulsed RF of the identified cutaneous nerve provides months of benefit.

What is narcotic bowel syndrome and how do I know if I have it?

Narcotic bowel syndrome is a paradoxical condition where long-term opioid use actually worsens abdominal pain through opioid-induced gut hypersensitivity and central sensitisation. It is suspected when a patient on chronic opioids reports escalating abdominal pain despite increasing doses. Treatment involves carefully supervised opioid tapering which counterintuitively reduces pain as the opioid is withdrawn. This must be done under medical supervision with appropriate adjunctive support.

Can chronic pancreatitis pain be controlled without surgery?

Yes, in most cases. Coeliac plexus block with local anaesthetic and steroid provides weeks to months of meaningful relief and can be repeated. Splanchnic nerve radiofrequency ablation gives six to twelve months of benefit and is repeatable. Lumbar epidural infusions are effective for acute-on-chronic flares. Surgery for ductal drainage or pancreatic resection is reserved for specific structural anatomical problems, not for pain management alone in most patients.

What red flags should make me see a doctor urgently for abdominal pain?

Seek urgent medical assessment if you have any of the following alongside your abdominal pain: unintentional weight loss, fever, blood in stool or vomiting of blood, jaundice (yellow eyes or skin), severe pain that wakes you from sleep at night, a palpable lump in the abdomen, or new onset of pain over the age of 50 with no prior history. These red flags require investigation by a gastroenterologist or surgeon before any pain management is planned.

What is spinal cord stimulation and how does it help abdominal pain?

Spinal cord stimulation involves placing a thin electrode near the dorsal spinal cord, connected to a small implanted device that delivers programmable electrical impulses. These impulses modify the way pain signals are processed acting like a volume controller on the pain pathway. The underlying source of pain may still exist, but the brain no longer receives it at the intensity that was disabling daily life. A mandatory trial period of five to seven days is always performed before any decision about permanent implantation.

How is an intrathecal pump different from oral pain medication?

An intrathecal drug delivery system (IDDS) delivers opioid medication directly into the cerebrospinal fluid surrounding the spinal cord. Because the drug reaches its site of action directly, the effective dose needed is typically one-three hundredth of the oral dose meaning dramatically less drowsiness, less constipation, less nausea, and better pain relief. It is considered for advanced cancer pain in patients where oral opioids have become either ineffective or intolerable.
