I'm really worried about my wife. She was diagnosed with TB in March and started on the standard treatment, but now she's dealing with back and neck pain, and stiffness in both areas. I've had some general physicians suggest getting an X-ray of her spine to check for Pott's spine, while others are saying an MRI of the whole spine or a CT scan of the LS spine might be better. Can you help me understand what might be going on and which specialist we should see? I'm also confused about why she might have spine TB symptoms when she's already on meds for TB in her lungs.

Yes .MRI spine is advised to the patient for evaluating potts spine TB..If TB spine is present pt needs ATT for another 6 months ,since it is extrapulmonary TB.
