This also explains why you have been having such a rough time with it. Besides which, no-one should be prescribed NSAIDs when they are on blood thinners. Most ill-advised.
And neither can you go without any pain meds at all - that's so cruel its criminal and totally unnecessary. You can have narcotic or narcotic-like drugs like Tramadol, codeine and hydrocodone. None of these have effects on stomachs like NASIDs do. But you need something! I despair of your doctors, they are not treating you sensibly or kindly at all.
