Thanks for your question on Health Care Magic.
I can understand your concern.
No need to worry for
stroke because cleaning solution can not cause stroke.
Possibility of
bronchitis due to inhalation of fumes from cleaning solution is more.
Any fumes, when inhaled for long duration, can irritate lungs and cause inflammatory reaction.
This is bronchitis. It causes breathlessness,
fever, Giddiness, uneasiness etc.
So better to avoid exposure to this fumes.
Breath in fresh air.
Consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).
If it shows obstructive airway defect than you may need inhaled bronchodilators and inhaled corticosteroid (ICS).
Don't worry, you will be alright.
Hope I have solved your query.
Wish you good health. Thanks.
