Thanks for visiting HCM.
You must have told me your weight, because I have strong doubt that for pyrazinamide
it was underdosing of the drug.
of bones and joints need 6-9 months of anti-tubercular treatment which must be adequately dosed and scheduled. It can be further prolonged if needed.
Don't worry it's a curable disease. But if symptoms recur even after 4th or 5th month of therapy, it will be better to go for culture and sensitivity of pus for acid fast bacilli to discover the drug resistance
Also there may be superadded bacterial infection needing antibiotic therapy....so consult your doctor if it is needed.
