Thanks for following up here.
I am glad to know that your lab reports including cholesterol are normal now.
However the improvement is likely due to antibiotics and not from cholesterol lowering medication. Palpitations associated with infection may have responded to the antibiotics when inflammation is down.
This time, all the three the Xray chest images loaded clearly show infiltrates in the right lower zone of the lung. It is suggestive of a pneumonia, although there could be non-infectious differentials. Allergy or sensitivity is unlikely. Xray shadows usually disappear after clinical improvement is apparent.
As you had no fever and had normal white cell count, non-infectious cause is possible or an atypical or resistant infection is possible which may not respond optimally to your current antibiotic. Night cough is usually due to pleural irritation (pleuritis)
What happened with the sputum culture report?
Please ask your physician or a pulmonologist if there is another cause possible or to try atypical pathogen cover with a macrolide or a quinolone group of antibiotic.
Sputum exam is must and SOS repeated. HRCT scan of the chest is useful for non resolving cases.
If you are not getting better, please do these things and take a pulmonology opinion.
Keep the crestor on. Keep taking mucolytics, steam inhalations, deep breathing exercises.
I would be glad to assist if needed.
