I am 22 years old girl. I'm suffering from extrapulmonary tb (brain and bone tb). I'm under medication now and it's been around 7 months. My health was improving. Last 4 days i'm suffering from cold and throat pain. And today i'm coughing out with mucus heavily like before (i mean I used to cough out heavily (dry cough) at the initial stage of tb treatment). What could be the reason? Can you please tell me as early as possible?
