I am not on coumadin yet but will probably be soon. I read thru the warfarin.com site and it eased a lot of my fears accept for the part where it talks about if you bump your head it can take a few days to find out for sure if you are ok. It says you should be very careful with head injuries and always get them checked. My question is if I bump my head on my car door while getting out of it (like i did yesterday), will i have to go get it checked every time and then wonder for a week if i'm ok? i am pretty clumsy and hit my head at least a time or two a month. I'm sure when i'm on coumadin i will notice even more when i bump myself. I have 2 young kids too and they are pretty rough with me, pretty sure i have had my nose cracked from being head butted in it a few times. I already get bruised pretty easily from being on aspirin daily. How bad is it really? How did you feel when you first came home from the hospital? Does the coumadin have any other side effects for you short or long term? I am scared that i will already be weak and crappy feeling from having a valve replacement and having to add coumadin on top of that will just be that much worse. Or do you not even notice you're on anything, just have to get use to taking it and testing?
