A member asked:

My son has small clearish blister like bumps on arm and face what could they be? they are itchy and appeared out of no where

A doctor has provided 1 answer

Allergy: Most likely an allergic reaction to something that he has been in contact with. If they are fluid filled blisters and he has not been vaccinated against chicken pox, that is possible although we don't see chicken pox often nowadays because most children are immunized against it.
