Sciatica
Definition:

Sciatica is a painful condition due to pressure on the sciatic nerve. The sciatic nerve is the main nerve that branches off and continues down to the thighs, legs, feet, and ankles.


Diagnosis:

The physician will recommend a series of clinical examinations in order to diagnose sciatica. MR neurography may help in the diagnosis of sciatica.


Treatment:

Treatment for sciatica will depend on the underlying symptoms that are present.


Symptoms and Signs:

Individuals with Sciatica often suffer the following symptoms: * Severe pain arising from the back down to the buttocks and down to the back of the legs. * Numbness * Muscular weakness * Impediment of movement or control of the leg


Causes:

Generally, sciatica is caused by lumbar and sacral nerve compression. In less common causes, sciatica may be caused by compression of the sciatic nerve itself. However, there are also a number of cases in which sciatica is caused by a different factor or medical condition like the following: * Spinal disc herniation, which means pressing on one of the sciatic nerve roots. * Spinal stenosis, which is a condition wherein the spinal canal narrows and causes spinal cord compression. * Piriformis syndrome, a neuromuscular condition wherein the sciatic nerve is compressed by the piriformis muscle. * Sacroiliac joint dysfunction due to unhealthy postural habits and insufficient exercise leads to both vertebral and soft tissue problems. * Trigger points caused by low blood flow because of injury or chronic muscular contraction. * In some cases, sciatica can also occur during late pregnancy because the uterus presses on the sciatic nerve and other conditions brought about by pregnancy.
