Maybe all the Kensington trash fire smoke is making its way to you. I used to walk to work in the summer and fall but when they started burning ANYTHING to stay warm I literally couldn't breathe walking. It's like chemical warfare here in Kensington. The toxic fumes are constantly in the air. It's horrible. It smells like what I'd assume a milk crate factory would smell like if it was burning down. ...Sigh. I hope you feel better.
