I began to be rather listless ,tired, unbalanced and drowsy. Ended up needing 3 blood transfusions, and now have to periodically get iron infusions. Said I had a slow bleed in my stomach over a 5 year period. I tok 800 mg of ibuprofen every day for over 8 years. I told my primary care doctor I was concerned but he said he did not want me to take a narcotic. I moved and have a new doctor who suggested a narcotic.
