Dear Mr Shankar
You have been diagnosed to have tubercular lymphadenitis
. The treatment for this condition as recommended by WHO is for 6 months. The regimen started for the treatment is appropriate.
Coming the surgery and the boils
that you developed then , it is difficult to establish the cause of boils all over your body, as most skin lesions are diagnosed based on the picture of the lesion.
In absence of a clinical examination, Your treating doctor is in the right position to identify the cause of the lesion based on the clinical picture.
If your symptoms are subsiding with the given line of therapy you must be getting the right treatment.
It would be advisable to have a detailed discussion with your treating doctor or seek a premium consultation with all your relevant records.
wishnig you a speedy recovery.
