I have these blisters that appear at the tips and around the nails varying in size from pin-head size to as big as the lead of a #2 pensil. They usually don't rise above the skin, go away in a few days, white scab form over. The skin looks transparent. When they do rise above the skin, they are itchy and sometime sore. They are usually filled with clear liquid, then go away a few day, many layer of white scab form over. When i accidently pop it, usually from itching, I see the blister created a hole in the skin, but no blood. Occassionally, they get bigger, forming white runny pus inside and a bigger gauge/hole inside the skin. Sometime, they 10-12 blister on one fingers ranging in size clustering together. Most are small and go away unnotice, other time they get larger and itchy. My doctor said it's dermetitis and caused by stress. But I hardly stress and they come on all the time, it's just that I don't notice it unless they itch. At any time I check I fingers I see at leave one or two on my fingers. They are tiny and don't bother me. Small ones sometime I can't see well; they are very visible when my skin is wet.
I want to know what cause them and get rid of them permanently. I had this when I was 20. When started, all the blister ends up forming pus and they were bigger, creating a bigger, deeper hole into my muscle. When they scab over I can see the many different layer of the dermis. Now, they hardly get to that stage. I guess my immune system had it in check--almost. I'm afraid that when my immune system gets weeker as I age, these blisters will became a bigger problem and be out-of-control.
