It was my eye doctor who first suspected I had vertebrobasilar insufficiency. This was before my left side became symptomatic with the vascular symptoms about 4 years ago. I have the dizziness, vertigo but not the tinnitus symptoms that you mention. I am hoping that by having the surgery, these other symptoms dissipate.

Like nospam, the symptoms seem to be brought on when I lift the arm up overhead. At times, my cardio workouts seems to trigger the symptoms, too. The right side does not trigger symptoms but the rib was removed 8 years ago and that side is still doing good.

On the left side, my vascular studies have progressively worsened over the years (pre and post-left sided TOS).
