atrial fibrillation
"Apparently helps my a-fib, but causes bad bruising and bleeding from minor wounds.  I also have bad heart burn and take antacid frequently. This happens while I'm eating, after, and also when my stomach is empty. A friend who tried Xarelto had the same problem, which makes me think it's from the medicine, or at least it made it worse. This causes me lots of pain and discomfort, but I don't know if another blood thinner would be the same."
