Thanks for your question on Healthcare Magic.
I can understand your concern.
Chest pain, cough and breathing difficulty are commonly seen with bronchitis and asthma.
Your discomfort is more when you are in polluted area. This means possibility of bronchitis is more.
So
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (pulmonary function test).
PFT will not only diagnose bronchitis but it will also tell you about severity of the disease.
And treatment of bronchitis is based on severity only.
You may need inhaled
bronchodilator and inhaled
corticosteroids on the basis of these reports.
And no need to worry for
high blood pressure. You can stillness control it with salt restriction in diet and exercise.
Don't worry, you will be alright.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
