The most common treatment for Raynaud's disease, assuming he really have it, is medically usually with what is known as calcium channel blockade. He will also need to avoid the circumstances that can induce the spasm. This usually means keeping her hands warm, avoid vibratory tools, avoid caffeine, anything that can constrict the arteries. If this is in your feet, the same applies. On rare occasions if you begin to have tissue loss then denervation of the arteries in either the hand or feet is the more modern treatment but it is difficult to find someone to do this operation. In the past we would do sympathectomies of the larger nerves and either the lower back if it involved the legs or the upper chest if it involved the arms.
