Ok Doc Lets Give This A Try. I Have Been

Ok Doc lets give this a try. I have been on "Fondaparinux" a sodium injection blood thinner for the last 3 years. I received a pretty bad human bite on my right forearm 5 days ago during a fight. The spot where I was bitten has a rather large lump and it's red and swollen. I am now seeing the bruising go don't to my right hand and up the back of arm to my armpit. I have done ice packs and elevation but it seems to not be getting better. But I don't have much pain. What do you think?
