I noticed one day that when i went to sleep i got a red mark on my back. It's flacky and it bleeds a lot. My grandmother is a nurse and she doesn't even know what it is. It just seems to grow bigger and bigger and I still have no idea what it is. I'm going to the doctors tomorrow, but I want some answers before I go to see him. So any suggestions?? *ERIN* :)

Erin, Since it seemed to have come on suddenly, could you have been bitten by something? Spider maybe? Spider bites can cause some pretty bad reactions.
Just a thought.
