Sciatica is a symptom rather than a condition. It consists of leg pain, which can vary from a slight crampy sensation to excruciating shooting pain that makes standing or sitting nearly impossible. Weakness, numbness, or a burning/tingling sensation in the leg, sometimes as far as the toes is also possible with sciatica.
Sciatica is a result of irritation to the sciatic nerve; the longest and widest single nerve in the human body. This nerve originates in the lower back and runs through the buttock and down the lower limb to the foot. The sciatic nerve can be irritated by inflammation in the spinal joints or discs or by muscle spasm. Not all sciatica is related to disc problems.
The term ‘sciatica’ is often wrongly used to describe all kinds of leg pain. In reality, there are many causes of non-sciatic leg pain; these are most commonly referred pain from the joints in the lower back or pelvis or muscular tightening in the lower limb.
Chiropractic can help to alleviate the symptom of sciatica.
