Hi Ruthie,
Welcome!
When your eyes or your mobility worsen or get a new problem, always call the doctor to get it documented, and try to make an appointment too.

These two parts of the body are so important you can not let it go without being checked. As for wobbly legs, in the meantime, try to stand with your legs a little wider apart. That gives a better stance and balance.

I have a vitreous detachment that is being monitored. I don't believe it is MS related. I have no pain but I do have a slight fog to look thru. My vision has not changed. I have had Optic Neuritis and this feels different to me. We are all different though.Have you eye doctor check your Optic nerve for pallor or swelling.

If your MRI is clear it may be a while before any diagnosis of any kind can be made. Some of us it took years, other very quickly. But don't neglect your eyes for any reason. Good luck to you. Let us know how you make out at the eye doctor.
