After a night out with friends, I stopped in a nearby cafe before heading home to use the restroom. Unbeknownst to me, the staff had just mopped the restroom with bleach. Usually, a clean bathroom is a welcome amenity, but this one in particular is very small (barely a water closet) with zero ventilation. Though I was in there a brief time, my eyes and nose began to burn and water, and I could not very well open the door until it was time to wash my hands. It's been well over an hour since I inhaled all that bleach, and my eyes, nose, throat, and lungs all burn. I can't taste anything, and all I can smell is bleach. My head also hurts. I've gotten a lot of fresh air and plan to go back outside shortly, but these side effects have yet to abate. Am I in danger of respiratory damage? Is there anything specific to this situation I can do to alleviate the pain and discomfort?
Thanks for your help.
