WHAT IS SCIATICA?

Sciatica can be said in different ways to patients, presently I am suffering from this sort of disease as per doctor and will be going for MRI dated 16/08/2010, which is a well known and important test for those who are suffering from back pain whether it is due to disc prolapse (bulging/herniation) or nerve inflammation. It is very rare that a medicine cure a patient completely from disc prolapse or nerve inflammation.  I am having leg pain and whole body has biting, sparking, burning like sensation because of my illness.  Medicines are somewhat helping to reduce pain but is not a proper solution to get proper fitness.
