Nerve pain can be sharp, shooting or lancinating and often involves pins and needle sensations as well as numbness. It typically extends from the spine and travels along the course or pathway of extremity nerves into the arms and legs. A common diagnosis for nerve pain involving the upper extremity is brachial neuritis. Lower extremity nerve pain often involves irritation to the sciatic nerve. Chiropractors specialise in locating where there is nerve interference that may be the cause of your nerve pain.
