Thanks for considering H.C.M.for your medical query.
After reading your query I came to know that your all symptoms are related to allergy
and irritation by chemical.
You may take now-
1- Anti allergic like Avil
are also helpful in such crises.
3- Anti inflammatory.
4- Steam inhalation & Warm saline gargling.
These above may help you but important thing is not repeat this situation in future and thus you should avoid use of these chemicals in future.
