question: I have had this problem for almost 2 to 4years now. It first started when my menstrual period would come. But, then it stoped for awhile and would not show up at all. Until, today it come out again. They look like rashes its very painful itch and when it goes away it turns into black spots looking like bruises. Its on my inner right arm, right thumb, left index finger. I hope to get answers. THANKS!!!!
