The symptoms of sciatica often include sharp pain, numbness, tingling or burning in the back of the legs. In severe circumstances, weakness in the legs can also be seen.The sciatic nerve is a large nerve that travels down the back of the leg to the bottom of the foot. It includes several smaller nerves and originates from the spine at the level of the low back. It passes under the piriformis muscles, which lies under the gluteus maximus muscle (main buttock muscle) on its way down the leg. Irritation of the sciatic nerve at any point along its path is commonly referred to as “sciatica”.
A diagnosis of sciatica, however, is often of little use to the sufferer unless it specifically indicates where along the nerve the irritation is occurring. Although entrapment of the nerve can happen in several different places, the two most common sites are where the nerve originates at the spine and where the nerve passes under the piriformis muscle.
Both cases respond well to chiropractic, although treatment can be drastically different depending on the cause.
