The Optic Neuritis and MS struck my eye, on this thread. I do not have UARS. Fatigue can, sometimes be a symptom, of my MS. And I do have bouts of insomnia.
My battle with MS began with, ON. I am the only one, in a rather extensive extended family with this illness, that anyone is aware of. I have a half-sister that has autoimmune issues and diabetes and thyroid cancer, she's 22. But not MS.

Hope you get some answers.
