How long have you taken treatment? Could u please send clear photographs of the rashes. One of the whole body to see distribution of rashes and close ups to see type of rashes. Also send me phographs of the medicines you are currently using. Does your son have fever? Is he eating properly? Sometimes it takes time to subside. If it is not a dangerous condition I will let you know and you can wait and watch. Has the rash subsided atleast a little after treatment? I will get a better idea of the diagnosis once you have answered these questions and sent photographs. Taking an opinion from a dermatologist is always welcome. But if you want a second opinion please take all the previous prescriptions and medicines to that doctor. Warm regards. Dr. Rajdeep Mysore. Chirag Hospital Bangalore
