I was in the hospital last week for an a-fib event, I have an artificial heart valve (aortic) and have been on warfarin since 2006. My INR was 1.6 when I got to the ER (should be closer to 2.5). They increased the warfarin a small amount and started giving me Enoxaparin sodium injections. I started getting large bruises at the injection sites and they have gotten much worse since I ve been home (Friday afternoon) 4/21/17. They told me to inject very slowly, which I have done, but some of the nurses did not and those are the worst sites. There s burning and large welts and my entire stomach area is black and blue. I can t get a call back from the hospital so far....Is there a way to make this more comfortable? Heat? Ice?
