It is quite common to get flu which can leave behind a bronchitis
temporarily. This is called post viral bronchitis and the cough and noisy breathing take about 2 weeks and in some even 4 weeks to disappear. If you are coughing up sputum it may be tested for TB and other organisms if you also have fever
, weight loss
, etc. especially since the CXR mentions the possibilities.
The tremors are only transient side effects of Salbutamol
My suggestion is that you must complete 2 more days of medications as advised by your doctor. She may ask for further tests when you follow-up with her, especially a CXR.
