Have an exam.: This sounds strange and I can recall nothing from my experience that could explain this. A doctor could have tested the fluid for the presence of blood (a guiac test) and also cultured the fluid. Blood blisters often appear dark, but usually are not on a stalk. Sometimes there are no substitutes for an exam by touching and feeling and looking with your naked eye.
