I get extremely tiny itchy blisters on my hands randomly. They are extremely itchy and are so small that they are hard to see. Sometimes they are itch so much I can't help myself and wind up scratching them. When I do I can see that there is a clear liquid that comes from them...not much though. I have been getting these random tiny blisters for many years now. I would appreciate any help and guidance that you can give me. I would like to mention that I have secondary progressive multiple sclerosis.
