Hi, I'm 45, married for 21 years and very very monogamous!! I noticed a pink spot on top of my foot,( all the spots began as tiny pink spots) it was itchy it got bigger n turned into a dark colored raised blister with a flat darker spot in the center that was a bit depressed, well the rash began to spread, and became painful and incredibly itchy, before I knew it it was on my inner arms, wrists, palms, ankles and arches of feet and torso!! If the blister beaks it weeps a clear fluid that dries a crusty honey color, the rash has come and gone for a little more than ten years it never out of control it's always been just a few spots in each area! The rash comes and goes within a few days to a week or 2, n it leaves a dark brown scar, even though nothing changes in diet, soaps, etc. etc. But now after all these years, I've noticed a few spots on my labials that feel and look raw,( from the moment i first felt the irritation of these spots they just looked raw, not pink spot like the others) I'm not sure if its related or not but I've never had any other symptoms except auto immune related symptoms, and symptoms due to a pituitary adenoma! There's no change in vaginal smell or discharge! N my husband has never had any symptoms at all!! I never really worried much until I started getting this on my labias ... N now I'm terrified!! Can u tell me what the possible causes are, good or bad?
