Thanks for your question on Health Care Magic.
I can understand your situation and problem.
No, this is not
anxiety related. By your history and description, possibility of recurrent
lung infection or
bronchitis is more in your case.
So better to
consult pulmonologist and get done clinical examination of respiratory system, chest
x ray and PFT (Pulmonary Function Test).
Chest x ray is needed to rule out lung infection. And if it is present than you need higher antibiotics because you are not improving with penicillin.
PFT is needed to rule out bronchitis.
It will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
You may need inhaled bronchodilators and inhaled corticosteroid.
So better to first diagnose yourself and then start appropriate treatment.
Hope I have solved your query.
I will be happy to help you further. Wish you good health. Thanks.
