it is true. it can take a while to dx (diagnose) MS.
sometimes sx's (symptoms) have to progress for tests to come up +.
MS sx's can mimic other illnesses. i'm sure your dr has been ruling them out, such as lyme disease.
it's so frustrating to know something isn't quite right but your dr can't find out what it is.
keep a sx journal with dates that certain sx's come up. that may help your dr over time.
