A Sciatic Nerve Block is an outpatient procedure for the treatment of lower back pain and leg pain.
A sciatic nerve block (SNB) is a single injection of steroids and numbing medication administered to the buttock into the sciatic nerve. It is designed to block the pain signal sent to the brain by a compressed sciatic nerve root.
This is the largest nerve in the body that runs through the lower spine, buttocks, back of the thighs and stops at the feet. When pain is present to this nerve it is called sciatica. Symptoms of this appear as sharp pain, numbness, tingling, burning, or prickling that typically start in the buttock and travels down the back of the leg.
You should have some pain relief immediately after the injection due to the numbing medication however, the steroid can take 2-5 days to take effect, pain relief can be expected for 4 to 6 weeks after the procedure. Relief will vary from patient to patient.
