Thanks so much for the great info and encouragement! My daughter is 14. Her optic neuritis wasnt too bad it was getting worse though before hospitalized. She had color dimness in one eye but had bad pain and blurriness in both eyes. It then spread throughout her face. Now to her arms and hands. Her strength still seems ok, is that a good sign? Just tonight she is complaining of pain in one knee and ankle. I am thinking this will remain a mystery for a while. If she does end up with an MS diagnosis, it's comforting to know there is great support and positive stories here
