Every person has its own experience. In any profession there may be some errors or misunderstanding. My experience with Dr.sud is overwhelming and I feel he is one of the best doctors in India.I went to medanta for my sons gastro problem. I found dr sud to be very composed and experienced doctor. Just two days of medicine and my son responded positively . He is a happy man so all of us. We r proud to have dr. Radnhir sud in India.God bless the doctor
