Hi NEET here is the thing, for indians the cost of the sergery is different than others such as foreigners. There are additional charges on foreign patients.
For your doubts regarding how good dr sarin is, let me tell you something. I was like you reading stuff online and believing whatever people used to post about the dr. However when i went to the guesthouse, i met people who have had tibia lengething before and were returning for femur lengthening. I interacted with all the patients face to face and all of them were full of praise for Dr sarin. I met around 8 patients who have done this sergery and were completely living a normal life afterwards. So thats the time i realized that people who post negative stuff about the dr have an agenda driving for some reasons. I suggest you visit the guest house and interact with real patients and ask them for feedback.
As for me i can say my sergery went very smooth. Today is DAY 3 and i have been removed from the epidural catheter. I can feel my toes, ankle and feets. No fever no vomiting no pain so i would only speak positive about dr sarin. He is very good and experienced.
