I had some minor ringing, major pressure and off balance issues. I would stand up after squatting (like pulling weeds) and almost fall over...or sometimes just while walking just teeter off to one side. That has subsided a bit, but the pressure remains as well as hearing loss. The hearing gets worse on the days where the pressure is worse. All this with a side of joint pain that can appear anywhere from neck and shoulders and hands to the more common in winter, foot pain while walking a lot or after laying down. or sitting with my feet up.
I had said immunologist because I wonder if this could all be allergy related. I read that joint pain could be an inflammation caused by an allergy.
An ENT was just where I started because I had to do something...
Oh, and unless this plays a role somehow that I am missing, the Hashimotos has been in check with the synthroid.
I thought it was interesting they were both autoimmune diseases and worth mentioning.
