It's me, back again. I have been having stomach issues off and on since my surgery in August. I was fine for a couple of months, which just happened to be the time while my INR was low (I'm convinced the coumadin, when in range, is affecting my digestive system but I could be wrong). Then it started up again, which was also while I was taking amoxicillan for strep throat. I already had an ultrasound of my stomach and a few other tests by my internist, which were all negative. Of course that's when we found out I had hemangioma's in my liver and cysts on my ovaries... gee, this is fun. Anyhow, get to the point, right? Stomach issues return so I'm referred to a GI dr. who I went to yesterday. Will be getting more tests, more meds, more ct scans, more fun. It's possible I could have antibiotic-induced colitis or an ulcer. Eventually, she wants to do a colonoscopy and endoscopy, but she said I'll have to go off the coumadin for these so she's not in a hurry, which is good. I was just wondering if anyone here has had these tests while on coumadin. How hard is it to go off? All I know is something about shots in my belly. Anyhow, thanks for listening to my ranting post. It was at least therapeutic for me
