Hi, This is Dr Chaithanya, have seen similar patients before. I have to continue answering as Dr Nair is not online.
I have seen the picture. It is like an Eczema. Can be triggered by either bacterial infection or due to any contact allergies or due to an immune trigger in the body. Now, you continue applying triamcinolone acetonide for one more week. Take a multivitamin tablet course for three weeks, apply regular moisturizers and see if there is any improvement.
If it doesn't settle down, You need to consult a dermatologist who takes a scraping and sends to pathology to know what it is!
