I have spoken to my doctor and he kindly told me to take red cell builders like vitamin b and folate, etc. So I bought some to strengthen up. He is arranging to use a cellsaver machine with me which is in a circuit and takes the blood that bleeds out and cleans it and puts it back in the body. Actually I read a report that it is less problematic that way in recovery. However I was reading about coagulation and I will definitely bring it up. It seems like it's supposed to have something to do with clotting, but I will ask because I want to lose as little blood as possible. (Naturally.) Another question to bring up. I hear there's less blood loss with hip surgery than knee surgery. I hope hope hope that I can walk better (less pain) after the hip surgery, but my knee is pretty bad also, but the big pain is from the hip.
