I have had sinus and now lung mucus discharge ( thick white and not green or yellow) for over the past five months. I have had allergy test, several CT scans and five rounds of different antibiotics. No change in my condition. Could this be from my blood pressure medicine?
Thanks for your question on Chat Doctor. In my opinion you are not having these due to your blood pressure medicine. You may have bronchitis. It is basically an inflammation of bronchi, which causes edema and more sputum production.  Whitish sputum indicates inflammatory process, not infective process. Do better to consult pulmonologist and get done PFT (Pulmonary Function Test).  This will help you in diagnosis of bronchitis. It will also give you severity of the disease. You may need bronchodilators and antihistamine.
