Captioned doctor always asks to book an appointment with him whenever we post questions related to dermatology. Practo users are literate enough to understand if a matter is not going to be sorted merely with qna will need diagnosis at least I know. So whenever question is posted response from this doctor like book an online appointment with me such a waste of valuable time for us. Dear doctor please understand we are posting question to know or understand problem not an opportunity for you to advertise freely. There are other genuine doctors who sincerely answer question and safely state to better understand situation please book an online appointment. Dr. Narsimhalu on the other hand only says book an appointment. Better refrain from answering questions like this. I need to also find way to flag doctors like this so that patients will have sincere answers from genuine doctors unlike Dr narsimhalu and practo will have better sincere doctor base than advantage seekers dr.narsimhalu
