My left wrist has a pain similar to a burn or scrapped bruise, but when I touch the area no pain can be identified. The pain has been with me for about a week. It is very hard to identify. Reminds me of when young when you skid your knee on a gym floor. This has no rash or visual identification. And when touched can not feel any areas that would get worse in pain when touched or pressure is applied, as if not there.
