I haven’t read previous comments as carefully as I’d like. But from what I did read, yikes! At age 17 It does sound mysterious. You had Lyme’s disease ruled out? One more thought, have you suffered serious trauma(s?) Most of us have by 17 but don’t recognize them as such. As you get ready to blast off to a new demanding phase of life, perhaps something needs to be resolved? Anxiety? Or have you been checked for early arthritis, seen an immunologist? (I get an eyelid flutter like a crazy cop in the Pink Panther movies when I’m under stress. And more…) Life sure does get weird & complicated as you grow. All best wishes to you.
