Suggest Treatment For Exposure To Fumes Of Blue Foam Styrafoam

i had a recent exposure (a month ago) to fumes of blue foam styrafoam being burned while hot knifed, which caused a sever reaction; burning airways, pressure in chest, diminished breathing capacity, eyeballs burning, heart beating hard. I have since been transferred to a location where I am not exposed to toxic fumes. However, I am suoer sensitive to all smells, dust, heating system, and I ve noticed that I can no longer fly up the stairs as usual, rather, when I approach the top, my legs feel weak, and finally feel as though they are fainting . My arms, as well, sometimes. After resting a minute or two, I continue down the hall, only to find a sever shortness of breath. Any ideas?
