I m having episodes where I smell smoke, but no one s smoking, and it feels like the air is getting thick, and I have trouble getting enough air. It s reocurring, frequently, so I don t believe it s panic attacks. I think it may have to do with sinuses, as I have been having sinus headaches and dizziness over the past month. If I have a sinus infection, is there a treatment option other than antibiotics and steroids?
