I have a blood blister that is about a half inch long, rises a quarter of an inch off and takes up the whole left side of one of the toes on my left feet. I got it because I have a wart and the dermatologist has been freezing it. The pressure is incredibly painful and I understand there is some risk of infection. I also think it is growing a bit in size since it now takes up part of the front and the back of the toe. It looks like its eating my toe and reminds me of pictures my high school anatomy teacher used to show me. Please help.
