Hello,
I cannot confirm anything without examination but it can be due to contact dermatitis or pityriasis versicolor. Treatment involves topical and oral antifungal medicines. Most cases of fungal infections respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine, ketaconazole and clotrimazole. You can consult a pharmacist and get any cream or lotion containing these ingredients. Some of them are Selsun, Lamisil, Monistat derm, Mycelex, and Nizoral. If the symptoms persist then please consult a dermatologist.
I hope it helps. Take care and please do keep me posted in case you have any additional doubts. Kind regards.
I went to the Dr about this awhile back. I cant remember what he called it, but he had me put Seltzon Blue on it before bed and then rinse it off in the shower in the morning. It worked like a charm after just a few days. It came back again this year, and I had to take an antibiotic to get rid of this time, but try the seltzon blue.
I have these same spots but mine are a little rough on the surface. They started last summer and I went to the doctor he said it was some thing ppl get once and it just goes away but now its back.
