Sciatica is defined as an inflammation of the supporting tissues of the sciatic nerves of the leg. This condition is characterized by a pain running from the lumbar (lower back) region to the back of the legs. Sciatica pains – felt in either one or both of the legs – are usually experienced after the age of 30, and go on aggravating as the age advances.
Causes of Sciatica
Compression of the spinal nerve due to ruptured vertebral disc in the spine, faulty posture such as slumping on a chair, sleeping in a curved position, injury that hurts the lower back region can be triggering causes for sciatic pains. Contraction of the piriformis muscle, which may lead to strangulation of the nearby sciatic nerve, can also be responsible for sciatica.
Symptoms of Sciatica
- Pain from lumber region to toe.
