Ever since I moved from the humid East Coast to the dry air of Calgary, Canada I've been experiencing this weird pressure/tingling at the base of my nose, where it connects to my face. It happens when I bend over to tie my shoes or even when I just tilt my head forward (chin to chest) to read a book or something. I do a lot of yoga and it doesn't seem to happen on the mat which makes me think that it's just when I'm not focused on my breathing. Even on this rainy day I can feel the sinus pressure sitting straight up and of course it worsens when I tilt my head forward. I should also mention that I have yellow bogies in my tissue which isn't typical. Do I have a sinus infection? I've never had any sinus issues in the past and I'm in great shape... it's just annoying. Thanks.
