Hello. Thanks for updating your problem here.
Usually, our body secretes submucous to combat the infection and to eliminate the infection from our body. When this mechanism gets interrupted or when the body gets infected with virulent bacteria, the secretions build up and result in symptoms such as those you described.
dust, bacteria, viruses and all other foreign particles are carried away towards the throat through cough. Thus, eliminating the infection and the pooled up secretions from the body. In your case, the green colored discharge, which you have described, could be a sign of bacterial infection. And tuberculosis is a disease caused by Mycobacterium tuberculosis.The presentation is very typical with cough, evening fevers and with a history of recent exposure to the contacts. You apparently, have neither of these symptoms.
antibiotics. I advise you to consult a physician for evaluating your present condition and the need for further management.
Hope this helps.
