Sciatica usually means discomfort or altered sensation in the low back that refers into the leg, knee and foot, though each person's symptoms may differ a bit. There are various causes of sciatica:
*Irritation of the Sciatic Nerve (one of the thickest nerves in the body) by compression of surrounding muscles
*Compression of the nerves that supply the leg and low back as they exit the spinal cord by intervertebral disc bulges, bony growths or fibrotic ligaments
*Damage of tissues like muscle, ligament, bones or tendons in the lumbar region which can then refer discomfort down into the leg
*Additional causes include disturbances with abdominal and pelvic organs and arteries but compared to the other causes these are extraordinarily rare
Because sciatica is almost always accompanied by low back discomfort there are similar risk indicators for both Back Pain and Sciatica:
A sedentary way of living is a great predisposing factor for a number of reasons, when someone is sitting for extended periods they'll be supporting the weight of their trunk, shoulder and head mostly on the low back and pelvis. This leads to a scenario where a comparatively little quantity of tendons, ligaments and muscles are supporting a very big component of your body weight. As the body likes loads to be spread around so loads are shared, lengthened sitting can end up in over load of areas of tendon, muscles and ligaments which means they get damaged and are not as good at supporting you afterwards.
Smoking is a predisposing factor thanks to the damaging effect on blood vessels. This increases swelling in the body and over a period of time can lower the amount of blood brought to an injured area by lowering the flow through damaged vessels.
Folks working in jobs that call for frequent lifting who haven't been taught (or do not use) correct strategy are also at bigger risk.
Treatments include Chiropractic, Osteopathy, Physiotherapy, Acupuncture & Massage.
Analgesic treatments can be useful at alleviating pain in a few cases.
