Sciatica is not a disorder. It is a symptom. It can be caused by continued pressure on the nerve running down the legs, called the sciatic nerve. It can also be caused by displacement of vertebrae in the lumbar area. Disc herniation or slipping can also cause the pain. A woman who is pregnant may have a misalignment due to pressure and movement from her child. Driving your vehicle with a wallet constantly in your back pocket can also cause the pressure on the nerve that results in sciatica. It can become severe enough to cause numbness or even paralysis in the leg or legs that are affected. A proper diagnosis is important. The chiropractors initial exam will attempt to find the underlying causes. This will be done by radiological studies such as MRI or x-rays. Electromyography may also be applied. These exam may not only find the potential cause for the pain but will also rule out any reason why a chiropractic treatment or therapy may not be what is needed.
