Can Laryngitis Be Caused By Exposure To Paint Fumes?
toxic laryngitis would sound strange but I can't exclude it
Detailed Answer:
Hello,
although laryngeal irritation can be caused by exposure to toxic substances, staying for 10 minutes in a painted house does not sound like enough reason for it. As you've noticed the workers did not wear masks and they were exposed to the potentially toxic substances but without symptoms (I suppose). If any of you caught a cold it's very likely that the other one would get it also because most viral respiratory tract infections are very contagious.
You'd better ask an Ear-Nose-Throat (ENT) specialist for evaluation of your condition. Direct visualization of the larynx may provide clues (signs of inflammation, mobility of the vocal cords, etc).
I hope you find my comments helpful!
You can contact me again, if you'd like any clarification or further information.
