I've Been Experiencing A Smoke Smell Which Nobody Else Smells,

I've been experiencing a smoke smell which nobody else smells, smells like wood burning. This has been going on for about 2-3 months. Now the last 6 days I've had a headache that wil not go away. I do not normally suffer from headaches. I've tried, extra strength Tylenol, Advil, Aleve, Tylenol sinus, nothing is making this go away. Could the phantom smell and the headache be connected?
