Ear fullness

It’s literally driving me insane.

I also have hard lymph nodes (prearicular and also down my neck a bit) that freak me out.

I also get fevers, dizziness, nausea, and hearing issues from the ear fullness.

Someone please tell me what to do? Stretches? Yoga? My night guard is making the ear fullness and jaw pain worse, but protecting my teeth. Idk what to do anymore. ENT, dentist have written me off so I’m going back to my PCP to ask for a PT referral. If I ever come across the money I’m considering Botox, but I worry it will change my face too much and I will get jowls where I already slightly have jowls from excess fat.
