@sahilbhaia03 I’m so sorry that you were unable to open the link. I can try re-pasting it to see if that will help. Here is a link to a large hospital:

What you will need to do is look up some of the large, university hospitals in your part of India and ask to see an internal medicine doctor. Are you working with your local doctor. He/she may be able to help by referring you to a specialist at a university hospital.
Also try this link: https://mayoclinic.org/about-mayo-clinic/care-network/members
Will you let me know if this helps?
