WHAT IS SCIATICA?
Sciatica is pain resulting from irritation of the sciatic nerve. The pain of sciatica is naturally felt from the low back to behind the thigh and radiating down to below the knee.
WHAT ARE THE CAUSES?
The main cause of sciatica is generally a result of a disc herniation directly pressing on the nerve. However any cause of irritation or inflammation of this nerve can reproduce the symptoms of sciatica. These causes include irritation of the nerve from adjacent bone, tumors, muscle, internal bleeding, infections, injury, and many others.
WHAT ARE THE TREATMENTS?
Traditionally bed rest has been used for the treatment of sciatica. Other treatments for sciatica include addressing the underlying cause, medications to relieve pain and inflammation and relax muscles, and physical therapy. Surgical procedures are sometimes required for persistent sciatica that is caused by nerve compression at the lower spine.
