There are several things that can cause the bruising. Mine started in college when I was taking aspirin for headaches and period pains. When I had to have surgery at age 19, I was told never to take aspirin again due to it causeing a delayed clotting factor in me. Switched to ibuprofen and alive with no issues for many years. After a blood clot in my leg (provoked by a spinal during labor) they gave me warfarin. I hemorrhaged. At menopause time I hemorrhaged yet again a couple of times. Years later I find out I have factor V Leiden… a genetic disorder that causes blood clots! I question how I can possibly be a clotter and a bleeder at the same time. After a TIA recently I am put on Plavix and Aspirin. Needless to say that caused serious bruises and I also ended up allergic to Plavix. Now they did a genetic study because I have allergies to lots of meds. Turns out I have a genetic disorder processing vitamin K…that causes bleeding and requires much lower doses of anti clotting meds. At age 70 I finally know how you can be a bleeder and a Clotter at the same time.
