Injuries of any kind need to be checked by a qualified doctor. Injured patients often decide to wait and see if the pain goes away and then if it does, they will think that everything is OK. That is not usually true as the pain is only an indicater of ongoing tissue distruction. When tissues have been destroyed, there is usually some pain. Some tissues have more nerve supply and are more sensistive than others, even though the support function may be minimal. Some improtant tissues may have little nerve supply and although seriously damaged, they may cause little noticable pain.
Sometimes the pain will subside and the body, although injured, will recruit other parts to assist so that relatively normal function can continue. This mechanism will eventually fail and cause other seemingly unrelated symptoms to appear.
Always call for a check-up whenever you have had any kind of an injury.
