Pain that radiates from your lower (lumbar) spine to your buttock and down the back of your leg is the hallmark of sciatica. Sciatica may be accompanied by numbness, tingling, and muscle weakness in the affected leg. This pain can vary widely, from a mild ache to a sharp, burning sensation or excruciating discomfort. Sometimes it may feel like a jolt or electric shock. Sciatic pain often starts gradually and intensifies over time. It's likely to be worse when you sit, cough or sneeze.
Sciatica is actually a sign that you have an underlying problem putting pressure on a nerve in your lower back. The most common cause of this nerve compression is a bulging or herniated lumbar disc. Piriformis syndrome is another common cause of sciatica. The piriformis is a muscle that lies directly over the sciatic nerve. If this muscle becomes tight or if you have a spasm in this muscle, it puts pressure directly on the sciatic nerve. Occasionally, sciatic pain in men is caused by sitting on a wallet.
The vast majority of the time, sciatic pain can be relieved through a combination of stretches, deep tissue massage of the piriformis muscle and chiropractic care. Occasionally, in cases where chronic spasm of the low back or piriformis muscles is causing the sciatic pain, it may be necessary to do a procedure called a trigger point injection, where a medical pain specialist injects a small amount of anesthetic directly into a spasmed muscle to break the spasm cycle. However, this is typically not necessary.
