I have been suffering from head aches, extreme tinnitus, disorientation, ear aching, burning tongue and a terrible metallic taste. Doctor says I have no infection and my symptoms are environmental. All started two months ago when I moved to a new apartment which has no screens so I can't open the windows. Also the street is extremely busy with unrelenting traffic noise and presumably dust. Am planning to move within the next few days. I'm wondering if this might be carbon monoxide illness and if my symptoms will go away.
