Dont be confused, Follow the medicine prescribed by the TB specialist, it will subside the infection.
If pain occurs then follow the suggesttion of orthopaedic or tb specialist. Pain can be managed by both.
But the main problem is not the pain but the infection. When Tb will be cured pain will be reduced automatically. Orthopaedic will do nothing special unless any necessity for operation arises so follow the tb specialist. A MRI
can actually asses the severity of disease progression whether it required any orthopaedic intervention or not.
Best of luck.
