I have also had the same issues since I was young, except they were on my hands. None of my GPs have given me any answers and only advised me to use OTC hydrocortisone creams. Last Dec they spread though and got worse! By Feb I had them on my scalp, feet and legs. They all start out just clear filled but quickly fill with puss, itch like crazy, sting when popped, and cause a lot of peeling around the site. They are very deep, and are everywhere on my feet and hands, legs and scalp now.
