Sciatica is caused by an irritation of the sciatic nerve. This nerve is about the size of your thumb and is formed by 5 nerves from the low back, runs through the buttock muscles and down the legs to the toes.
You have a sciatic nerve for the left leg and right leg.
Causes of sciatic pain can be most commonly subluxation in the spine ( spinal bones that get stuck in motion), disc problems, stenosis and arthritis.
Chiropractic can help all of these causes by adjusting the spine to free up the sciatic nerve along with specific exercises. Your MD will not know how to do this and therefore will only treat your symptoms with pain killers, anti-inflam meds and muscle relaxers. I have lectured to many medical groups and I can tell you that they have had no education when it comes to spinal biomechanics so do not rely on them to treat your sciatica just like you would not rely on a chiropractor to treat organ diseases which your MD is skilled at.
