Hi, i'm new. i'd like to ask a question...?

Whilst I see that the location of a lesion will affect which part/area of the body/mind is affected, my question is, what if there are more lesions on MRI than there have been effects?

What i'm saying is, i have a c6 lesion that accounts for my left arm and facial signs and a t6 lesion that accounts for my newer right leg stuff.
But i have numerous brain scars too. I had 'Bells palsy' last year (that wasn't) but nothing else springs to mind.

Where did the other lesions come from and how come they were 'silent'?
