Before I went on warfarin I brused easily, not even knowing why I had got some of them but since being on 5mg warfarin a day and an inr of 2.2 I don't bruise anymore a couple of weeks ago I fell down the stairs and hurt my hip and knee I was in so much pain I had to go to casualty, it was 4 days before I could even put any weight on it,I was sure that I would be black and blue over a large area but not even one tiny bruise has come out. I banged my head on the corner of a chest of draws and I got a big bubble on my temple straight away then it just went leaving a 2inch circle of yellow
