Ringing in the ears is a common symptom of of candida and/or heavy metals. I have it off and on while chelating, and when I break the diet.
Having it happen 24/7 is worrying though.
I suggest you find out more about yeast, and, if it makes sense considering your symptoms, try an anti-yeast treatment and see if it helps.
I also suggest you find out about heavy metal toxicity and see if that may be an underlying cause of any yeast trouble you may have.
