How Can Allergic Cough Be Treated?

I am very allergic to chemical fumes of all kinds. I accidentally breathed in spray paint fumes and my throat became immediately raw. It has been three days and my throat is the sorest today and I ve developed a nasty cough as well. I feel generally ill and depressed today. I was exposed at work where an individual went outside to spray paint a small piece of plywood and then came in with it before it had dried and may have given it a few touch up sprays inside as well. I am not sure how to prove to the individual at work and my boss that my extreme discomfort was caused by their extreme disregard for safety. Any professional advice for me?
