The transforaminal epidural steriod injection (ESI) is a long acting steriod injection into the opening at the side of the spine where a nerve root exits. This injection, while using the same technique and fluids as a cluneal nerve block, is for pain relief in the limbs, not the lower back. The procedure uses a long acting steriod that when injected reduces the inflammation and swelling of spinal nerve roots and tissues around the nerve. This will reduce pain and numbness as it focuses on healing the inflammation and swelling of the area.
The procedure will be done under local anesthesia. The patient will remain awake during the procedure so they can give feedback to the physician. The patient will be on either their back or side, whichever is best optimize the X-ray picture that the provider will be viewing. Patients vitals will be monitored. Under X-ray guidance the needle is placed and the steriod is injected. After the injection, your arm or leg may feel heavy or numb, but patients will retain full movement of their limb. Patients will have some soreness and aching for a day or two after the injection and most begin to experience pain relief 72 hours afterward. while using the same techniques and fluids as a cluneal nerve block, is for pain felt in the arm(s) or leg(s) of the patient versus the lower back. Just like a cluneal nerve block, the goal is to reduce inflammation and swelling of spinal nerve roots and other tissues surrounding spinal nerve roots. This will help reduce the pain, tingling, numbness, and other symptoms patients feel that are caused by the inflammation and swelling.
