Ear feels clogged, sore throat one side for 6 months, NOT sinus…what can it be?

I keep going to doctors and they give my antibiotics, but they don't do anything. 3 times I've done this. My regular physician said if it was sinus it would have gone away by now. I've also been getting all this pressure in my head. Some sort of ear/throat infection? Also they've tested me for strep (twice) and my tonsils are already out.

Answer:
I had similar problem. Feeling pressure and ear clogged, I had it in both ears but much more on one side. It was sinus. I was prescribed nose drops and ir helped, then I consulted with ND, and she recomeded natural product “HMC”. It really worked for me.

At about same time I had a problem with throat pain on one side, the physician said that when it is on one side, it is most often from the stomach. I was prescribed Nexium, and it went away.
