There have been a number of posts on bruising lately (including mine). Don't forget that spontaneous bruising can indicate serious health problems and should be checked out. If a bruise appears where you have not bumped into something and it is not tender when you press on it then it may not be an ordinary bruise. In my case my platelets were too low and I got whacked with a kidney infection and foot infection that I have not been able to fight off. Had to go totally off my immunosuppresant and it has really knocked me down. Anyway, just make sure you do not have a more serious problem if you are bruising.
