The sciatic nerve is the longest nerve in your body. It runs from your pelvis, through your hip area and buttocks and down each leg. The sciatic nerve branches into smaller nerves as it travels down the legs providing feeling to your thighs, legs, and feet as well as controlling many of the muscles in your lower legs. The term sciatica refers to pain that radiates along the path of this nerve.

What causes Sciatica?

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.

How is Sciatica Treated?

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.
