This procedure is often done on an outpatient basis. However, some patients may require admission following the procedure. Nerve blocks usually take only minutes to administer.
You will be positioned on a table or other surface to allow the doctor access to the site(s) to be injected. The doctor will then identify the spot the needle needs to be placed, using palpation and/or imaging guidance.
More than one injection may be required, depending on how many areas of pain you have or how large an area needs to be covered. The doctor will most likely tell you when he or she inserts the needle and when the injection is done.
When finished, you will be allowed to rest for 15 to 30 minutes to let the medication take effect. The nurse will also make sure you don’t have any unexpected side effects before you leave the doctor’s office.
