Sciatic Nerve Block

About the treatment

The sciatic nerve is essentially a bundle of nerves within the spine that helps control sensations and muscle function in the lower extremities. Conditions like herniated discs, degenerative disc disease, or an injury to the lower back can cause compression of the sciatic nerves and result in pain or other symptoms. This is a type of nerve pain also known as sciatica. It is classified by causing radiating back pain that shoots down the buttocks and legs.
Initially, the patient will be brought back to the procedure suite where the skin is prepped with sterilization and local anesthetic to numb the skin and reduce pain. Live fluoroscopy (x-ray) is used along with an injected contrast dye to identify the pathway of the nerve block needle and proper needle placement. As needle position is confirmed, a sterile mixture of local anesthetic and steroid solution is injected into the targeted nerves. The needle is then removed and the physician applies a bandage over the injection site. Patients will then be observed in our recovery suite before being discharged for recovery.

After the treatment

Patients are observed in our recovery area following the procedure to evaluate for adverse effects and pain relief. Common mild side effects can include nausea, dizziness, or soreness around the injection site after the procedure and should wear off after a few days.

Light activity and rest are recommended for 24 hours following the procedure. Patients may then resume regular activity as directed by their physician. If any complications or infections arise, we urge patients to contact your Desert Pain Specialists provider as soon as possible.

Patients should begin to experience pain relief within the first few days of the injection however full relief can take up to two weeks due to the corticosteroid used. Pain relief varies however injections typically provide between 3 and 6 months of relief. The procedure may then be repeated in the future if needed.
