<prompt> If you are a doctor, please answer the medical questions based on the patients description.hi, i am 22 yrs old.i was exposed to tb patients alot of times because of the nature of my work. i went to a dr. today, and have an examination done. negative CXR. i think it was 4 yrs ago when i first thought that i might be infected. my chest and throat hurt alot because of coughing 4 days ago. i also got a fever 38C yesterday and 38.38C today. if i have a possible tb, will there be alot of complications because my tb was not diagnosed earlier ?  <response>: Hello rearward welcome to Chat Doctor.come have evaluated your query thoroughly. If you had TB since 4 years, you would not have been in this health condition at present, so do not get panic about that issue. So far as complications of the undiagnosed TB is concerned there are many as if we consider pulmonary TB - hemoptysis - cathexis - weight loss - anemia - breathlessness - fever not controllable - protein deficiency - others. Hope this will help you for sure. Regards.
