i have suffered for years from chronic inflammatory sinus disease and have headaches, face pain and 'stuffy head and nose feelings' and intermittant balance problems when walking or laying down. . For the last few weeks I smell burning like a smouldering bushfire or something is going on, but nobody else can smell it. They all say the air is fresh. It's worse in humid weather. anybody else experience this 'burning ' air sensation? I have shut the doors and windows when watch TV in the night because it smells like the room is full of smoky air it's so noticable. ??
