Hello to all of you! I have this red rash in the feet legs and thighs, 7 years ago it started, i usually still have it but not worst but now its starting to go back and its a lot. I had seen a lot of doctors and nobody can tell what is it and the dermatologist that took a biopsy and still did' not find anything! Im very worried about it that i don't know really what the cause and how to treat it! No pain no itch its just lots of little rash under skin and when its in the worst it gets big! I am asking help if anybody knows about it! Thank you very much!
