Is it normal that i had little blisters on my fingers and what causes it?

AIDS

I get them too, like red pressure sort of blisters if thats the same. If you carry heavy bags then this can happen

If you write a lot, that could be a reason.

I get these from dry skin. My dermatologist told me to use a moisturizer after each bath, and hand lotion after washing my hands during the day, and it helps.

Misuse of fingers can cause blisters.
