sonds like an std you *****
I get blisters on the thumb side palm of my hand when i eat to much wheat and dairy--its a rare form of eczema a dermatologist told me.
I just got these bumps on my fingers after being in the sun. I have had them before, but didn't know what they were. An additional item to consider. I also received a fever blister at the same time. It was on my lip and on my skin near my lip. I believe I rubbed my finger on it. I read that fever blisters can form on your fingers from rubbing it during the secretion phase. I believe these bumps are either 1. an allergic reaction or 2. a fever blister/herpes simplex 1 infection.
I'm currently leaning towards the fever blister theory. I did this by opening some of the bumps and itching it more. This then caused more bumps to form near by the original bumps one day later. This would mean it is an infection, because I had the previous bump for a while. Whatever I was alergic to had already been washed off days before. I had not been exposed to any thing else either. I think these bumps are fever blisters! They just act a little different than ones on your lip. In addition, I read that fever blisters can be on your lips, face, mouth or FINGERS!
I also read that exposure to sunshine can cause fever blisters!!
