Pinched Nerve in Low Back

A “pinched nerve” occurs when there is excessive pressure on the nerve roots that exit from the spine.

This can be caused by a mechanical compression of the nerve as it exits the spine (such as from a herniated disc, enlarged bony and ligamentous tissues of the spine), or from local swelling.  Often, a pinch nerve will cause shooting pain, numbness, tingling, down the leg in the distribution that the nerve innervates.  This may also result in weakness or loss of reflexes. Often times, X-rays can be helpful as an initial screening tool.  MRI maybe indicated if nonoperative treatment fails, there are red flag symptoms, or if severe nerve impingement is involved. Red flag symptoms include decreased sensation or motor function in their lower extremities, bowel or bladder issues, fevers or chills, recent weight loss or weight gain, or strictly night pain which may indicate more serious conditions. Initial treatments include activity modification rest, oral or topical anti-inflammatories or analgesia, muscle relaxant,  physiotherapy, massage or chiropractic therapy, acupunture, and bracing. Spinal injections may be helpful for both diagnostic and therapeutic treatment. Surgical interventions may be indicated if patient has failed nonoperative management, or if condition rapidly worsens.
