Well they tell me I have PNH which is basically hyperactive nerves. I twitch all over everywhere all day. Been like this now going on 2 years. I’m sure if something sinister I’d know by now. I am still skeptical about the “artifact” even though the doc that read it said I probably moved and caused the ghost shadows like thing that showed up. Kind of scare me bc he first said something about MS but when I told him I didn’t have that he said oh ok must of been you moving. I’m going to ask for another MRI. Switched insurance and have to get referrals so it will probably be a few months before I get an MRI. What did you find out? Did MRI show artifact for you?
