Could Smelling Wood Burning, Hypertension, Dizziness, Sweating, Persistent Headaches, And Brief Lapses In Awareness Indicate A Serious Health Issue?

I have smelled wood burning for the last 3 to 4 days. My blood pressure had been running high for the last couple of months at least. I had to come home from work this morning due to dizziness, profuse sweating, and another headache, that I have had for the last 2 weeks. Today I had an episode where I was talking to my husband, and I sorta checked out for a few seconds. He said I had a very funny look about my face and my right hand.
