Transforaminal injections can be performed to the cervical, thoracic, or lumbar regions of the spine. The injections can help alleviate pain associated with radiculopathy, displaced intervertebral disc, or sciatica. The needle is injected into the foraminal space near the nerve root. A local anesthetic and steroid medication is injected into the foraminal space to help alleviate swelling and inflammation of the affected region of the spine. There is a possibility of numbness to the affected extremity following the procedure. This numbness is temporary and should be relieved within hours after the procedure. Many patients receive this injections as a series of three.
