I recall, quite a few years ago now. I went through a period where my eyeballs themselves would bounce up-&-down. In particular I recall having gone to a play & sitting in my seat, waiting for the play to start while my eyes bounced up-&-down. I don't recall how long that went on for. I don't think it continued for too long. But it was all just pent-up anxiety. Hope things begin to improve for you soon.
