Rabbit specialist vet in pune/pcmc area

My rabbit is unable to walk properly he is 5 years old . Since few months he had this problem we used to take him to vet give him medicines he used to recover and but this time nothing is working and the vets aren’t of that much help. He used to drag himself in the beginning of this condition but now he can’t even stand on his own legs . Took him to a government vet at aundh but it’s not been of much help . The vet says it’s nerve damage and given medication regarding that but his condition is only worsening. Please help me out here . His right leg has close to no strength and now his right hand is also showing similar signs . Please suggest me some good rabbit specialist vet . I love my bunny a lot and i can’t see him like this please help
