Can ms be missed on an MRI?

Hello. New here.

A couple of weeks ago I was rushed to A&E with altered sensations, tingling / burning / hot and cold water feeling. I also lost feeling in my bladder and bowel and numbness along my legs.

Neurologist mentioned MS and ordered an urgent head and spine MRI. They came back normal and sent me on my way saying they weren’t sure what it is.

My question is, could MS still be a possibility or is an MRI the best way to diagnose?

It’s been about 2 months now and my skin feels so off. Bladder control has come back.
