Sciatica is the term given to pain down the leg, which is caused by irritation of the main nerve into the leg, the sciatic nerve.
Rod Dunn welcomes you to the Sciatica Clinic
Looking at this website probably means that you think you may have sciatica but are not sure. What you DO know is that you literally HAVE (not are) a pain in the bum! What you want to know is what is it, what caused it but most of all how do you get rid of it!
What is Sciatica?
Technically speaking, sciatica is a symptom not a diagnosis It is a non-specific term commonly used to describe symptoms of pain radiating downward from the buttock over the posterior or lateral side of the lower limb. It is usually assumed to be caused by compression of a nerve but this is not necessarily so.
A common neurolgical cause of this pain is entrapment of the sciatic and/or posterior femoral cutaneous nerves. But the pain may be caused by trigger points in the soft tissue. This latter case is easily overlooked and requires manual palpation of the musculature associated with the hip if the pain is not to be misdiagnosed.
Background
It is often that there is sciatic nerve root entrapment, resulting in the compression of the nerve. Pain and symptoms being transmitted or referred from the low back to one of the buttocks and down the back of the leg along the pathway of the sciatic nerve. Hence the term sciatica.
The exact cause of sciatica is not fully understood but is commonly thought to involve a slipped or herniated disk. This means one of the disks, which lie between each of the vertebra in the lower back (lumbar area), has cracked and allowed some of the inner disk material to protrude out, putting pressure on the adjacent nerve root, which in this case is the sciatic nerve. The term 'lumbago' is often banded about as well which is a general term for low back pain. However, some people have been found to have a slipped disk but have no pain.
Sciatica Symptoms
Alternatively, it may only come on when sitting or standing in a certain position. Clinical experience indicates that these certain positions are usually associated with continually holding a poor posture either at home or at work. For example, protruding the head forward peering at a computer all day or regularly lifting a baby out of the back of the car. But some or all of these symptoms are also associated with other conditions which is probably why the name is often misused as a catchall word for any pain affecting the buttocks or other parts of the leg. In this case the pain is triggered by a local trapping (trigger point) or straining of the nerve along its pathway.
