i'm sure this has been addressed before, but i'd like to hear from as many as possible. i've read of many who have had to take coumadin (wayfarin). is this STANDARD treatment? is it age/health related? i had major back surgery (lots of fun hardware and my own/cadaver bone graft, it's kind of cool), and they had me in those lower leg squeezy things to prevent clots, but i didn't have blood thinners. i'm concerned also that, because i can't take celebrex, i take 800 mg of ibuprofen 3 X day (plus the usual suspects, flexeril and percocet), prescribed by my back surgeon. i remain under his care until his partner does the hip. i don't know if ibuprofen acts like aspirin, but i would really hate to schedule surgery only to find out i have to have it out of my system (i'm not to give blood this time, because our time frame should be only a couple of weeks from now). i guess that's two questions. yes, i should be asking my doctor. i have a hunch he's getting tired of me calling twice a day! any thoughts?
