Mysterious bruising on feet my husband has bruising on his feet-the bottom heel and alongside the big toe and on some of his toes but did nothing to bruise them. what can cause this?

Chances : Chances are this has nothing to do with the feet, but more a problem with blood clotting. It may be showing up in the feet because feet take more of a daily pounding than the rest of us. I would recommend he go to his primary care physician, who will undoubtedly order some blood tests and see if he has some kind of coagulation issue.
