Hello!
Tinnitus is no fun ... I've had it as long as I can remember. I too had many severe ear infections when young and always assumed that was why. During my last visit to a neurologist, I mentioned that I had tinnitus ... and he replied, "So do I."
His answer to my question is there anything to do about it was a simple NO. I have to agree with hockey that loud noise should be investigated as a possibility. Good luck with your md visit.
