My wife has been infected with TB in the month of March and the treatment has been started immediately. Combination of rifampicin, isoniazid, ethambutol, and pyrazinamide is been given to her as per her weight. She has low haemoglobin (about 8) and iron deficiency too. And for the same , medicines are given to her ( Iron, folic acid , vitamin C ) Now from last 10 days....she is having back pain in the back and around neck. What could it be now ? What are all the test needs to be done ? TB spine ? Could it be that ? If that is the case then she is already under TB medication. Help me, please. What's the next step ? What other tests should be done, besides LFT ?
