I have a burning feeling sometimes in different parts of my body and?

I was just wondering if I inhaled some propane gas from a grill, when it was taken apart with gas in it ; it made a hissing sound. I was not standing on top of it, but i was a few feet away from the tank. I am so scared. It also seems that steam is coming out of my mouth and nose at times. Please give me your opinion? Thanks!
