I've seen a neuro, and I just had a brain and spine MRI this past weekend. I was in the machine for 1.5 hours, but lying there flat on the table made my left arm hurt really bad from the neck down. It was starting to get unbearable toward the end, and I "called" the radiologist with my squeezer to ask if I could move my arm. I'm usually not brave enough to speak up for myself about minor stupid things like that, but it HURT

Anyway my neuro mentioned possibly needing to do a spinal tap but said not to worry about that for now. But it still freaks me out! Lying still for the MRI was bad enough, but lying very still on my side for a needle to be pushed into my back??? I chose to be awake for my wisdom teeth being taken out, but this is a different story!!

Unfortunately I have a tremor in my leg when I do a sort of rockette pose as my neuro described it, lol. That's the main thing that worries me. I've had it for almost a year but I associated it with straining(?) my hip. Just noticed it one day. Occasionally since then my knee will also give a little while walking after I've been sitting (only happens like once a month or less). But a couple weeks ago it was happening a lot for 2-3 days. This symptom has since disappeared again. Not sure what's really going on there!
But the symptom that brought me to my primary doctor recently were these electrical/tingling sensations. I started getting brief zaps in my leg with the tremor. Didn't think much of it. But a couple weeks go by, and then I got tingling zaps under my collarbone and in my left arm. It was very constant for a few days. And annoying! My primary doctor ordered blood tests and referred me to a neurologist. My primary said my blood tests were normal, although my neurologist wants me a little higher on B12 so I've been on that for a full 3 weeks now. Still getting zaps but maybe it hasn't kicked in yet.
The only other thing worrying me is that my reflexes were weird in my leg with the tremor. When my neuro used the hammer, my leg kicked but then it kicked a second time for no reason!! He also said something about me kicking far. I feel like I was nervous and maybe jumpy, but I definitely didn't intend to kick twice. This ever happen to anyone else? Do you think you were just nervous?
I apologize that this is so long. All this stuff just keeps going through my mind and I want to get it out somewhere. I don't think I necessarily have MS, but I am worried I could have it. I mean, even if I did have it, I'm doing pretty well right now all things considered. Still a bit frightening though because I know it can progress and I've seen it progress, and I just graduated college and got a new job. I don't know. On the bright side, my neurologist was super friendly and funny! Definitely took his time with me and was thorough. I feel like I'm in good hands if something does show up.
