For over a year now I have a blister that come and goes on my scalp. I firstget a burning sesation in my scalp and the a blister. Clear fluid comes out with some blood. I went to a derm Doctor and he say I don't have a fungus and he prescibed a ontiment and gave me a shot. But the blister re-appears in the same place and now the blister have shown up other areas of my scalp. Most time it's only one blister.
Dr. do you know what this is.
