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.
