Hi and welcome, congratulations on your sober time, that is great. How frustrating to be dealing with these other symptoms though. Surely they can be worked out with the help of a doctor. Are you able to get a second opinion? I haven't the slightest clue what it could be, but one thing that immediately comes to mind is water in your ear. Which could come from swimming or even bathing. You could try those ear candle things. If it is water it'll fix it right away, if it is not, there is no harm in having a good clean out anyway. I had a friend that had tinnitus, ringing in the ear is a symptom of that but she had many more symptoms to go along with it.
It could be so many things- most of them small things- only a doctor could figure it out.
That has got to be so annoying though, I'd really try to get to another doctor as soon as you can.
Do let us know what you find out.
