is once diagnosis is confirmed most it should clear off in 2 to 3 weeks time maximum. Some time there may be issue of drug resistance
when it can be delayed or some complication takes place. Normally after injections oral drugs may be given along with good healthy diet and care of potable water some vitamins
may be supplemented to help in recovery.
Some times when diagnosis is in question? hidden tuberculosis
in body may be there ??
But your doctor knows best discuss with him.
Best of Luck.
