I am suffering from tuberculosis from 1 year. After 6 months of treatment of tb I developed koch's lymphadenitis in neck. Then after I taken high dose of first line drug along with streptomycin for 2 month. But lymphadenitis got worsen (increase in size). Then we go for mdr tb test my Gene xpert shows low MTB, not resistance to rifampicin. And afb culture shows normal (no acid fast bacilli seen after 42 days. I am 2nd time tb patient first in 2008 (abdomen tb ). Now what should I do .i still have low grade fever and lymphadenitis. I am currently on r comes and ethambutol from 1 month and I discontinued this medicine for 1 month. Is this okay.
