I am having Lymph node TB and I have completed my 10 week of treatment. After 7th week my lymph node started to grow and become painful. After 9 week of treatment my Doctor took out some 20 ml of pus out of the grown lymph and sent that sample to Lab for further test. After 10 week I came to know from Lab report that the TB bacteria is still not dead and has grown. My question is, how long does TB bacteria normally take to die after start of TB treatment? What should be done in such situation?
