Any Connections to Neck Problems and/or BPPV (Vertigo)?

I've noticed a correlation between my neck and the symptoms of tinnitus. When my neck is out of whack, the ringing is the worst. And after a good neck/back massage or chiropractic adjustment, the ringing actually stops for a few days. I have chronic back aches from a hockey injury to my mid back. I've always wondered if there could be any real connection between the spine and this damn ringing.
Also, I developed BPPV (vertigo due to inner ear imbalance) about 3 years before the ringing started. I always wondered if there is a connection there a well.
I'm with Kaiser and am surprised how helpless they are with tinnitus. Very frustrating.
