SciaticaSciatica (Sciatic Neuralgia) is a form of low back pain characterized by intense pain radiating in a pattern associated with its dermatome. A dermatome is the area of skin supplied by nerve fibers from a single nerve root.
Hence by knowing the areas of skin involved we are able to trace which nerve root(s) are involved with the problem. In the case of Sciatica the pattern is down the back and/or side of the leg, generally crosses the knee joint down to the leg and foot, and may be either on one or both sides, along the distribution of the sciatic nerve.
Sciatica is caused by peripheral nerve compression, disc herniation, degenerative joint disease, sports or occupational injuries, fractures, infection, spinal tumor, back strain, or spondylolisthesis (slippage of one spinal bone over another).
If not treated, pain may become more intense, neurological symptoms may become more severe (Numbness, tingling, muscle weakness and possible atrophy, sensory loss, and diminished reflexes), and quality of life on a day-to-day basis will be affected.
