### output:

Hellos you mentioned that there is a tuberculosis in the back (in my opinion this may be extra pulmonary tuberculosis after FNAC report). But dosage you mentioned of anti-tubercular medicine is not perfect (in my opinion). The dosage are adjusted according to weight wise as:Rifampicin 8-9 mg /kg body weight. Isoniazide 10 mg /kg Ethambutol 16-18 mg /KgPyrazinemide 25-30 mg /kg. In my opinion this treatment should be for initial 2-3 months according to severity of symptoms (known as intensive treatment) . After this 2nd treatment started depending on condition of disease 6 months to 1 year (total). As about tuberculin test, still you may have disease. In my opinion consult a Tuberculosis physician and get his opinion about all these. In any condition patient should not develop resistance to anti-tubercular Chat Doctor. Hope this will help you.
