Hi.
I have been diagnosed with tuberculosis disease, but me and my family doubts this diagnosis.
I had a tuberculin skin test which appeared to give negative results.
After a week of coughing with smelly phlegm and fever, the fever is gone, the phlegm is not smelly anymore and I have little to no cough at all anymore.
Though I did have an x ray thrice which showed an activity in the right upper lobe of my lungs, i still don’t think it’s tb.
could it be some other minor illness?
i feel perfectly fine and energetic right now. could it be a wrong diagnosis? thanks in advance.
