I read your post and can relate to the problems you have with your ears. What I found this last year is that I have Meniere's Syndrome. It is an inner ear disease that causes short term memory loss (in some), feeling spacey or inability to concentrate and make good decisions, dizziness, vertigo, tinnitus, balance problems and hearing loss of the lower tones....and complete hearing loss in some (usually only in one ear only, but can be bilateral). I was diagnosed after having an "attack" that seemed to present as a severe headache or migraine, dizziness when looking down..then looking up again, or turning my head too quickly...not to mention nausea, anxiety, and terrible audio problems. I even felt dizzy when I was sitting, riding in a car, or watching things move past me.....watching tv! It was very scary at first because my head felt "full".... I tried allergy meds and decongestants that did not work.
I was treated for a sinus infection first because I have been prone to them, but after the symptoms didnt go away I was referred to a local ENT. Once I was referred my mother reminded me to tell the doc that she had been dx with Meniere's 30 years before and they should test me for it, as it can be familial. After an MRI and a hearing screening I found that I have it too. One way to treat Meniere's is with allergy shots.
They tested me for all kinds of allergies and the worst offender was mold. I have been on allergy shots for 9 months now and feel so much better. I still take allergy meds, a water pill, anti anxiety meds, and watch my sodium intake.... I notice a big difference if I don't take the meds and eat too much salt.
I just wanted to say something because all of my symptoms were present at one time or another for several years, but didnt present together until I had an actual attack. The problem is that the inner ear is very close to the brain. The signals the brain is getting are warped somehow by the fluid in the inner ear....balance, eye problems, thought processes are all disrupted as your brain adjusts to the problem...but this causes the brain to also trigger anxiety because it (the brain) is getting mixed signals....so it sends mixed signals.
This syndrome can not kill you, will not cause cancer, pain or any other harm to your body, but it is definitely a pain in the neck! Whether you have Meniere's or not, the fluid in your ear can cause your brain to send the wrong signals to the rest of your body. I would definitely have a CAT scan of your sinuses, and be tested for allergies. You might mention meniere's to your ENT as well. It can't hurt to be tested....usually an MRI and a hearing test will confirm or deny.

I hope this helped in some way.
