Hi,Dear,Thanks for your query to HCM. Dear I read your query and reviewed it with context to your query facts. I understood your health concerns and feel Concerned about them. Based on the facts of your query, you seem to suffer from- Chronic bronchitis with Pleuritic pain in left chest-wrapping around left shoulder blade. This pain is from chronic bronchitis with clogged up terminal alveolar groups,causing pleural inflammation from infection. X-ray chest may show few dense shadows with thickened pleura-which indicates edematous thickened inflamed pleura.. In your case as the cough is with productive yellow mucus, indicating enough infection of air track. Possibility of Pneumonia, accompanying with this is more and needs to be kept under watch, by closed observation. But the afebrile body,with this yellow mucus indicates recovering Bronchitis with pleuritic pain in left chest laterally and in back near left shoulder blades. Pneumonia would be indicated by high fever with chills which is not there in your case. Exhastion is from chronic infection with dehydration and destruction of vital lung lining tissue, from productive yellow cough. Possibility TB Bronchitis with Pleuritic pain is to be kept in mind.For this to find out-AFB sputum / PCR tests of yellow mucus to find out TB antigen of live/ dead bacteria/ IGRA-blood test to detect hidden subclinical TB. Exhaustion may indicate TB infection with no fever/ or mild fever. Course of Augmentin duo(Amoxycillin with clavulanic acid ) may differentiate NON-TB cause,if it responds to this course for 10 days time. Supporting it with high protein bland diet with plenty of fluids / vitamins would recoup you soon from this condition. Hope this would help you to plan further treatment from your doctors there. Welcome for any further query in this regard. Good Day!! Dr.Savaskar M.N. Senior Surgical Specialist M.S.Genl-CVTS
