I've been on TB meds for a couple of months now and feel pretty good, but I'm still a bit worried. Before all this, I was dealing with a fever for about a month and lost a lot of weight. A chest CT showed those enlarged lymph nodes typical of TB, and my ESR was just a tad high. But after getting an EBUS Test and FNAC, all my reports came back negative, even the AFB culture. The doctor still thought it was best to start the TB treatment. Is it normal for all the tests to be negative even if you have TB?
