Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of inhalation induced
bronchitis is more in your case.
Bleach contains chlorine, fluorine etc. These chemicals, on inhalation, cause irritation and inflammation.
And these all lead to bronchitis. Bronchitis causes breathing difficulty.
Best treatment is inhalation of fresh air and avoidance of exposure.
Antihistamine and anti inflammatory drugs are advised if coughing and pain are present.
Inhaled bronchodilators are needed if patient is having breathlessness.
So you needs inhaled treatment with antihistamine and anti inflammatory drugs.
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.
