Thanks for your question on Health Care Magic.
I can understand your concern.
No, I don't think your current breathlessness and past history of operation are connected.
You are having chronic breathlessness.
And it is commonly seen in
bronchitis or
asthma.
So better to
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest
x ray 3. PFT (Pulmonary Function Test).
Chest x ray is needed to rule out other lung diseases.
PFT will be needed to diagnose asthma or bronchitis. It will also tell you about severity of the disease.
And treatment is based on severity only.
You may need inhaled bronchodilators and inhaled corticosteroid (ICS).
So better to first diagnose yourself and then start appropriate treatment.
Hope I have solved your query. Wish you good health. Thanks.
