Thanks for your question on Health Care Magic.
I can understand your concern.
You are having inhalation
lung injury.
This type of injury commonly causes inflammatory reaction in airways and
bronchitis.
These cause tightness in chest.
Treatment requires avoidance of fumes, breathing of fresh air and plenty of fluids orally.
It takes almost 1 week for complete recovery.
But if you still feel
chest tightness even after 1 week or develop
wheezing or breathlessness than you will need inhaled bronchodilators, inhaled corticosteroid (ICS), antihistamines and anti inflammatory drugs.
So wait for 1 week, you will mostly improve.
Hope I have solved your query.
Wish you good health. Thanks.
