I have been suffering from bronchitis for over a week and have been taking two Keflex tablets twice day since Friday. My coughing during the day has subsided, however, at night, the mucous wakens me with a severe coughing bout. My mucous has been clear . This morning I did notice a yellowish color. I have been pushing fluids and notice my energy level decrease. How would I know if this turns into pneumonia? I am a non-smoker.
Thanks for your question on Chat Doctor. In my opinion you may have either pneumonia or bronchitis. Yellowish sputum suggest infection. You also feel low energy. Which is again a sign of infection. So get done chest x-ray to rule out pneumonia. Get done PFT (Pulmonary Function Test) to rule out bronchitis. So I advise you to consult pulmonologist first and get done above things. You may need higher antibiotics too.
