Medical Negligence

Hi, I was operated for an ACL reconstruction in 2014. My leg was supposed to heal within 6 months. I visited my doctor multiple times and he never did an examination if my leg was stable or not when I repeatedly told him that it was painful and not working fully. I left India in 2015 to pursue my Master's in USA. I recently went to an Orthopaedics surgeon here and he told me that my ACL graft is not functioning. I was told by my doctor in India that he'll use a Xenograft to do my surgery which is using a horse's ligament for a graft. My new doctor in USA wanted to use a part of my hamstring for the same surgery. Post my surgery he tells me that he was unable to find the part of my hamstring which he wanted to use for my surgery. His conclusion, my hamstring was taken out by my Indian doctor. My question: Should I be suing him for medical negligence and stealing a part of my hamstring? I'm a complete stranger to the judicial system in India and hence your advice will be really helpful. Regards Aditya Chaudhary
