My father has a pacemaker, and in a nursing home, in very poor health, the batterie went dead last week and we were to go see the doc Monday, to discuss getting new batteries. His heart doc, said, taking him off his cumin would be a risk and really did not want to do it. Today he has blood coming from his penis. Can you explain what is going on with him, they are taking him off of his cumiden and aspirin.
