hi doctor , i m 15 and for the past year i have been getting small patches of dry skin on my upper arm, and recently i woke up with a large (about half the size of the palm of my hand) brownish patch of dry skin on my breast, its not itchy but sometimes a little sore , is there any thing i should may be do or anything it might possibly be ?
Hello dear your problem is not looking grave it looks as if u r most probably suffering from Chat Doctor.  U can apply lactocalamine. Or it could be fungal infection. Visit a dermatologist.
