Sciatica is a condition where the sciatic nerve becomes entrapped or pinched. Sciatic nerve pain typically originates in the lower back and runs down the buttocks and the back of your legs is often described as sharp and shooting occasionally burning or electric but can also be described as cramping and aching. In more severe cases of sciatica, there may be an associated pin and needles or numbness.
Sciatica can be caused by a variety of different structures such as tight muscles, lumbar disc bulges or herniations, and misalignment of the lumbar spine. Pain can be triggered and made worse from coughing, sneezing, or prolonged sitting, though it usually only affects one side of your body.
