Hi, I am 27 years old. From past 4 months I am undergoing medication. Earlier doctor said I have pneumonia and undergone treatment for 40 days. Then later on 15 days before in ct scan it was diagnosed that I have tuberculosis. I am taking medicine from last 15 days. Now I feel very tired, headache and nausea. Please suggest what to do. And for how long I have to bear this and undergo treatment for tb. As I am working I really feel exhausted and over exerted at the end of the day.
