Life line hospital is one of the worst ones in Chennai. It is also the costliest hospital I have ever been to in India(hospital I visited in past include Appolo, Wockhardt, Manipal etc).
From my personal experience with Dr. Rajkumar I can say he is an ever hungry wolf. For simple stomach pain he asked me to get admit. HE told me so many scary diseases name that I was totally scared. He made more than 10k for no problem. Thank god that I did not agree to get admit otherwise god knows what could happen.

If your life so think properly before you hand over control of your body to any wolf.
