Jennifer,
I'm not sure what your doctor meant by a "ms episode." I think you should call him and ask him about it.
Do you have an appointment to see the neurologist he is referring you to? in my humble opinion, I definitely think you should go.
I wish I had some more info for you. I hope the doctors are able to find out what is wrong ASAP and you're soon on your way to a speedy recovery!!! WFEN
