I am facing stomach problems from 2018 in between I go through the treatment but after some time it gets back to the same problem. In Pune I visited one Dr. Kothari Endoscopy Aundh Pune. He wrote many tests for a total cost of 15k plus. So I never visited him again. It was too costly for me. I heard Nagpur is Something like hub of good Drs they say. Suggest Me pls.
