Yep, this is the physical manifestation I am most struggling with right now, too; not because I worry that it's anything serious, but simply because the symptoms themselves are very good at triggering anxiety, and anxiety really makes the symptoms worse, so it's a difficult cycle to break! With allergies acting up lately, my ears and head feel like they are going to burst. They hurt all the time. I'm always feeling off-balance, and occasionally will even feel "spinny". I wake up with my ears feeling like they're full of cotton, my eyes are puffy and red and watery, and my jaw clenches up as I sleep because of the pain and anxiety, which makes it so much worse. I have to constantly remind myself to relax my muscles. The feeling of imbalance makes me want to hermit at home and not go anywhere, but in the long run that makes it so much worse. I force myself to get out and do things, and while it's hard and uncomfortable and sometimes even scary, it's really the best thing you can do to just try to keep getting on with your life.
