I do not recommend the doctor
What struck me was his poor diagnostic skills. How can anyone arrive at a conclusion about a skin condition by simply looking at it, without a physical test (scratch test, prick test, or related procedures) to rule out other possibilities? The sad state in many hospitals is that doctors tend to treat the patient like they are idiots, lacking in any ability to understand their own problem. This is one such doctor. Also, he lacks any basic social skills. Hardly impressive in clinical, and basic bedside manners. I would not visit him again.
