Hello fizzyrox and welcome to NeuroTalk.

There is a diagnostic Criteria for Multiple Sclerosis (The McDonald Criteria).

You may want to read the impression section of the MRI report as that will usually give some indication of findings, but is not a diagnosis. Unfortunately, non-specific could mean just about anything and is a very general term.

In the diagnostic process Drs. look for "signs" of what may be the cause of a patient's symptoms. Signs include Neurological exam and testing. Symptoms are those things that we, as patients experience. Right now it's doesn't sound like you have enough "signs" to support a diagnosis of Multiple Sclerosis.
