I had very bad experience with Koramangala, Bangalore Doc Chetan Ballal, for a minor problem he have given Heavy doses of Anti Biotics and he continued his treatment for almost 2 months(It was sore throat infection, I consulted other doctors later on and found he was making fool and asked to get various test reports from his own pathology lab).
It is really hard to get a good doctor in Bangalore.
Please beware and keep distance from those kind of doctors.
