Thanks for writing to us.
The treatment provided to you is basically to cure tuberculosis. So now in your case, the first thing required is to confirm whether the lesion that you are having is tubercular or non tubercular. the same can be done by a skin biopsy
. If its cutaneous tuberculosis
then medicines need to be given for 6 months. initially in first phase of two months a combination of four medicines- rifampicin
and isoniazid is given then for 4 months isoniazid, rifampicin, ethambutol is given. Right now you are taking two medicines only rifampcin and pyrazinamide.
I would advise that you use Ask a specialist feature of this site and upload the image of lesions, treatment taken so far and investigation done so that we may discuss the treatment options in your case as without seeing the lesion it would be difficult to ascertain whether it is tubercular or not.
Hope this helped.
