<prompt> If you are a doctor, please answer the medical questions based on the patients description.Dear doctor, I was diagnosised with TB infection in my left upper back by ultrasound guided FNAC in february 2013, Medications: from March to May 2013 1st 3 months i took 4 tablets daily contained Rifampicin 150mg Isoniazid 75mg Pyrazinamide 400mg Ethambutol 275mgtablet. Then from June to December 2013 next 7 months i took 2 tablets daily contained Rifampicin 300mg Isoniazid 100mgtablet. In December 2013 i had the TB skin test which was 12 mm. Then from januray 14 to april 30 i again continued the second dose as usual. But still now i feel a pinch type pain inside while i stretch my left upper back muscle. Please give me your valuable suggestion whether i should go for the surgery now to get rid of the infection.  <response>: 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.
