Hi there. Thank you for posting your question with Healthcaremagic. I will do my best to help you.
I wonder if this might not be a form on psoriasis
. I would use a strong corticosteroid ointment like Dermovate
Ointment on it. Apply thinly about three times a day until you get it under control.
I hope that I have answered your questions fully and been of some help. If you have anymore questions please contact me again anytime.
Dr Andrew Rynne.
