If I was you I would discuss the headaches with my doctor and ask the doctor what would be the best thing to take. Many people take
Tylenol for their headaches, but not more than 2000 mg total a day. (Keep in mind, many over the counter medication contain Tylenol, so be sure to read labels.)
Because of the previous esophageal bleeding, aspirin should be avoided because aspirin can cause bleeding.
