Perhaps he meant to say that weakness and fatigue are not exclusive to MS. They are symptoms of many other things including but not limited to: CFS, Anemia, Obesity, Pregnancy and Depression.

Maybe there are other things going on that need to be addressed too. Maybe not by a Neurologist but a different specialist.

Could you be anemic? Maybe a nutritionist can help insure that you are getting good iron and other essentials.

My fatigue was at its very worst at the time before my heart valve surgery.

good luck with everything.
