Possible to get polymer flu fever from pot of boiling water?

Polymer flu fever happens when teflon used on nonstick pans get heated to certain temperatures. I accidentally left a nonstick pot on a heater with max temperature to boil some water. I forgot about it, and when I got back about 45 minutes later, the windows of the house had gotten steamy, and I also think there was a weird smell. There was still alot of boiling water in the pot, but the day after I have developed this mild cough and an ickyness of the throat. Is this polymer flu fever. Although the temperature of boiling water is far too low to cause damage, was the temperature of the pot itself much higher? There was no visual damage to the surface, no bubbles or malforming that I could see.
