Hi. Greetings. Could you send pics of your lesions on private chat ? That would be helpful to diagnose your condition. Do your patches itch when you sweat? Probably you may be having tinea versicolor which is bit a serious infection but see a dermatologist in your city and get treated with antifungal as prescribed. Let me know if you need any further assistance in this regard. Warm wishes, Dr Govind S Mittal, Excel Care hospital.
