What inspired your MD to put you on Amox? Was any testing performed? Any other meds?

I suggest asking your doc to order a ear swab and culture, and a sinus swab (or sputum) culture. Be CERTAIN it is held for 2-4 weeks while observed by lab. In fact, I would insist on a culture.

And I would toss the Antibiotics .

I may know. If you have had your ears checked and are told they are ok. Look here. This sounds like tmj or a bad neck. It happens to me and hundreds of others. I have to pop my ears to level out the air pressure in the ear tubes. In the car it can get trapped in there. Annoying and painful. It took me years to figure it out. POP pop pop, drives a person crazy.went to 3 ear nose throat doctors, assuming it WAS my ears. Nope.
The upper neck, the Atlas and axis, can effect the inner ear. It is like a quarter inch away form the inner ear. Lots of people with titinitis, and dizziness, vertigo, plugged feeling in ears, Possible cause? their upper neck or jaw. Your neck or jaw may not even hurt, but can do this.
It can effect the sinuses too, because they do not drain properly from the face.
If you get weird eye symptoms too. I have trouble focusing. Blurry, then clear, and all sorts of vision disturbances, warped, tunnel. If you have this 6 years already. Try a chiro. Maybe. Think about what I say. Dont know much about candida, but when it comes to this, i know my stuff.
Look here. This is a great site made by a fellow in austraila. UPCSPINE.COM.
But a person doesnt need what they call a NUCCA chiro, and regular good experienced one should spot this in a second. Course allergies, and sinuses can do this. But 6 years? its not sugar. Your right, your ears, nose and eyes are out of balance. Hope this helps. Go see a chiro Please? cindy

You are describing symptoms I've had off and on for a while. My symptoms usually return when I break the candida diet (though my symptoms are much less than before).

My ear problems are most severe on an airplane because I pretty much have to break the candida diet if I want to eat anything and the change in altitude when we land can cause shooting pain in my ears. I find one of those menthol inhalers people use when their noses are stuffed really helps with that symptom for me.

I recommend finding out more about candida (yeast) and heavy metals (especially if you have silver fillings, but you can get heavy metals from other sources). Chelating heavy metals is what has helped me the most with my symptoms, while anti-yeast treatments helped me feel better but didn't provide a lasting cure.

If you're going to take the antibiotic, then I've read it's best to take probiotics after you finish to help keep the good bacteria in your system. I believe it should be used a few days after you finish, otherwise the Antibiotic will kill them too. It would be better not to take the Antibiotics at all, but it depends on the severity of your symptoms.

If you do have a yeast problem, the Antibiotic will help with a symptom, but make other symptoms worse later on.
