Thanks for your question on Health Care Magic.
I can understand your situation and problem.
In my opinion, you should
consult pulmonologist and get done clinical examination of respiratory system, chest x ray and PFT (Pulmonary Function Test).
Fatigue, difficulty in breathing and
wheezing are seen in
lung infection,
bronchitis etc.
So chest x ray is needed to rule out lung infection.
PFT is needed to rule out bronchitis.
You may need antibiotics, inhaled bronchodilators and inhaled corticosteroid (ICS).
So consult pulmonologist and discuss all these.
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.
