I am not sure if this could be TMJ so that is why I am asking. I have had ongoing sinus problems and terrible symptoms which could be both TMJ related and allergy related. My symptoms include: plugged ears with painful pressure (ENT says my ears like fine though and that there is nothing wrong with them), very bad dizziness and vertigo which gets worse the more plugged and pressure are on my ears, intense brain fog like I'm here but I'm not here kind of feeling, occassional ear popping when swalling or moving my jaw that usually never helps unplug them, sinus headaches and pressure all over my face and head, swollen glands, jaw pain that goes from the bottom of my jaw up to my ears. I have had a very bad habit, that started when I was a child, of chewing on the sides of my mouth. I definitely notice my ears plugging up more while doing this and my jaw hurting. Today my jaw is very painful and I am feeling even dizzier than I normally do. Is the severe dizziness and brain fog related?
