Well, for me it started with sinus problems.I would get sinus headaches and pain in my ears. When my sinuses become inflamed, it screws up my eustachian tube- causing the "dysfunction". My ears will start to feel plugged, I might feel fluid in there. I will get dizzy, and feel like my head is not attached. I had allergy tests done- all negative, so I know it is not that. So, I have non-allergic rhinitis. when I get stressed out or dont exericise, I notice a flare up.
