Great information. Thank you David and all.

Joanna, I know it's not fun for anybody to be suffering from any of these issues, but I feel a little less alone knowing somebody else relatively "young" is having similar issues.

I had an MRI this morning to rule out MS. It was my very first MRI and I am a very anxious person, so of course I had a full blown panic attack when they put me in the machine and I had to be taken out twice. My mouth, face, and even teeth were tingling and buzzing during my panic attack, before they ever turned on the machine. Sure made me think about how a stress reaction contributes to nerves. Anyway, I did eventually get back in that tube and I made it through the entire scan. Growing up at age 30! hahaha
