@Grivusangel -- That doctor knows what he's talking about. My sister ended up in the hospital with internal bleeding because she was taking ibuprofen for her arthritis, and decided it wasn't working well enough, so she took aspirin, too. It relieved the pain, but she started bleeding internally because the two meds together thinned her blood too much.
Her GI doctor had a talk with her about mixing medication and how she could have gotten herself into real trouble. As it was, she had to have three pints of blood in the ER. Her hemoglobin was way, way too low. She had to have a Vitamin K infusion, too. It was nuts. I thought she had better sense than that.
