I get this as well. A lot of times it is because my body is out of alignment, so a trip to the chiropractor helps. I take Claritin during pollen season, try to stretch shoulders and neck to keep the ears from stopping up. I use the saline rinse and avoid strong smells. An ice bag helps a ton, or alternating ice/heat--see which works for you.

You might be experiencing a TMJ problem--temporo-mandibular joint disorder, where the jaw is out of alignment, and it affects the ears regularly. I went through 10 years of splint therapy to help with this after a blow to the head and jaw. It was horrifying.

One of those night guard splints from the drug store (for your bite) is a good place to start, it helps some. If you go to the doctor, I am almost certain that most insurance companies do NOT cover TMJ therapy, so avoid that term if at all possible. I was treated by an orthodontist for that over many years. It is very expensive, but it worked. I do not wish that on anyone...

I'm looking into Lymphatic Drainage by a qualified physical therapist that is an expert in this.
It will help us with ears, nose, and throat. Helps the whole system that's trapped with toxins.
I've used a Neti Pot for the sinuses. Gone to an ENT who cleaned my ears but didn't understand the pussy liquid build up or my tinitis, ear ringing.
Wishing you well.

All the time either both. Plus I have a constant ringing jn my ears and significant earing lose.

Get a lymph massage.. drains the fluid and gives immediate relief.. my experience.
