Sciatica

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 do I know if I have sciatica?

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.
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.
