Sore throat for the past 11 years?

About 11 years ago (when I was around 26-27) I started having a sore throat. I went to see doctors, did a lot of test, even got a camera shove in my nose and nothing came out of it. Tried various type of anti-acid, nothing. One doctor told me I had sleep apnea so I got a CPAP machine, didn't help either. Another doctor told me I have allergies and not sleep apnea and gave me a spray but still got a sore throat.

I do have hernias in the neck from an accident I had when I was 24 so I have no idea if it plays into the situation, no doctor told me that though.

I'm now 38 and the only times where I didn't have a sore throat were the only two times I stay awake for more than 24 hours, but that was years ago and obviously not something I want to do again.

Does anyone had or has something similar, did you find a solution.
