Sciatica is a set of symptoms including pain caused by general compression or irritation of one of five spinal nerve roots of each sciatic nerve—or by compression or irritation of the left or right or both sciatic nerves. Symptoms include lower back pain, buttock pain, and pain, numbness or weakness in various parts of the leg and foot. Other symptoms include a "pins and needles" sensation, or tingling and difficulty moving or controlling the leg. Typically, symptoms only manifest on one side of the body. The pain may radiate below the knee, but does not always.
A Spinal disc herniation (prolapsus disci intervertebralis) is a medical condition affecting the spine in which a tear in the outer, fibrous ring (annulus fibrosus) of an intervertebral disc (discus intervertebralis) allows the soft, central portion (nucleus pulposus) to bulge out beyond the damaged outer rings. Disc herniations are normally a further development of a previously existing disc "protrusion", a condition in which the outermost layers of the annulus fibrosus are still intact, but can bulge when the disc is under pressure. In contrast to a herniation, none of the nucleus pulposus escapes beyond the outer layers.
Fibromyalgia (FM or FMS) is characterized by chronic widespread pain and allodynia (a heightened and painful response to pressure). Its exact cause is unknown but is believed to involve psychological, genetic, neurobiological and environmental factors. Fibromyalgia symptoms are not restricted to pain, leading to the use of the alternative term fibromyalgia syndrome for the condition. Other symptoms include debilitating fatigue, sleep disturbance, and joint stiffness. Some patients also report difficulty with swallowing, bowel and bladder abnormalities, numbness and tingling, and cognitive dysfunction. Fibromyalgia is frequently comorbid with psychiatric conditions such as depression and anxiety and stress-related disorders such as posttraumatic stress disorder. Not all fibromyalgia patients experience all associated symptoms
Problems with the spine and/or nervous system can often be the causes of poor posture. Chiropractors are trained to be able to detect whether or not their patient has good posture. It is very important to treat poor posture because it will likely develop into worse problems as time goes on.
Chiropractic treatment can be very effective in minimizing the effects of physical stress being exerted on the body due to pregnancy. Chiropractors who treat pregnant patients will have a special table that adjusts to make room for the belly at any stage of pregnancy. Weight gain and changes in posture during pregnancy can result in misalignment of the pelvis and increased curvature of the back that can cause a significant amount of pain and discomfort.
