@racors I too have RA & OA, but haven't experienced what you describe. However, I also have periodic vertigo, and have noticed if my tinnitus begins to sound like bells instead of buzzing in different tones, I am about tom get hit with a bout of vertigo. Most docs I told that to just look at me like I'm crazy, but my current ENT nodded and smiled when I described it. She said "more people should listen to their bodies."
