Hello NoWakes,

Welcome to NT.
Sorry that you are going through this...the road to diagnosis can be a rough one .
It is usually best to take one day at a time and listen to what your body... as well as to what the docs have to say.

It is quite possible to have MS and a clear MRI; especially if an MRI was not done of the spine. Even then, some spinal lesions do not show up either.
It sounds like you are in good hands with your doctors so far though.
It seems that they have run some of the tests to exclude other possibilities and have chosen to use a strong anti-inflammatory to get things under control ASAP.

From there it might be a bit of a wait and see approach. Please let us know how you are making out with the prednisone and how things go afterward.

With love, Erika
