Good medical help is the first step in treating an injury. There is a running underground which can recommend local doctors who treat runners. Talk with some long-term runners. Every injury requires special treatment and you want to find the specialist who has successfully treated the greatest number of similar problems. Until you see a doctor you might want to keep the injured area higher than your head or at least off the floor as long as you can. This helps remove blood from the injury so that fresh blood can flow in greater abundance.
