Sciatica is a group of symptoms and not an illness. Pain, weakness, numbness, or tingling may run down from the lower back down a leg to the foot. Symptoms may be caused by a herniated disc, pinched spinal nerve roots, trauma, or rarely tumors. Pain medication, hot and cold packs, physical therapy, steroid injections, and surgery help relieve sciatica.
