Hi there. You should be impressed by any doc who calls on a sunday night! However, unfortunately, I cant comment on what he told you. I know very little about spinal issues, and not having any lesions in my spine makes me even less able to talk to you about it.
I have over 50 lesions in my brain and black holes- if you want to discuss that!
however, what you did say he told you, doesnt sound like MS related things. Streaky increased signal? Thats not a lesion...Im not sure what it is. Im hoping someone else with more spine issues will chime in to help. Its good that you are having the brain MRI- that will help rule out or show any lesions which could also be causing your pain. By that I mean, I have so many brain lesions, that they affect things like my hands and fingers...I have no use of my left hand, and yet, the hand is FINE. ITs the signal to the nerve which is damaged..
Keep us posted and hang in there, someone will chime in.
Hugs
Nikki
