Rohit,
I'm glad you have recovered from the accident and I hope you can find help with your physical movement. But the purpose of this website is to help people who have bone marrow failure diseases like aplastic anemia, not problems like yours.
I suggest that you contact the
Indian Orthopedic Association and the
Indian Association of Physiotherapists to ask what kind of specialist you should see, and how to find one. You can also contact nearby hospitals, or the medical schools at nearby universities, to ask if they can refer you to a specialist. For example, the
Fortis Hospital in Kolkata might have someone who could help you.
