I am still undergoing TB treatment and will be doing xray test and probably a sputum test as well in May. I not sure about TB though since I don't have cough and other TB symptoms which I used to have last year. Also my xray from January was good according to doctor. But as you said, I am also worried about reappearance. Even then I wonder, I never had this issue during peak of my TB issues. I used to have cough with phlegm sometimes which was red or yellow. Red because my lungs started to get damaged and it was blood staining my phlegm. Right now, it's just clear , almost like saliva but thick and coming from chest. My weight has remained the same as well throughout the last 5 months.
