On medicines, inhaler for bronchitis. Having coughing with metallic taste. Green sputum with heavyiness in the upper bronchi. TB?

Dear Dr. Christensen, About a month a go I was on a Z-Pak with and Quvar inhaler for basically bronchitis . It did get better but what I noticed is in the mornings following I would cough for a bit till things cleared and then it would go away. I also noticed that when I would go for a walk and the air was a little colder I would start coughing and that metalic taste was there. Yesterday it started again with clear sputum but the metalic taste was very strong and all night long I had strong deep coughing fits . This morning green sputum again. My upper bronchi area feels slightly heavy and all stinking night long on exhale they would crackle. This was annoying. I am drinking lemon and ginger tea to help with my throat. My lymph nodes are not swollen in my neck which they were last month. I notice when I breath through my mouth deeply is when the hard cough is triggered. The inhaler does slow down the coughing. If I am running a temp it is very low grade. I work as a dental assistant and was thinking I just picked up something but now I am wondering if I should get checked for TB. Any ideas after that long explaination
