HI again!
I remembered our last discussion right away:

Browsing through your posting history, it's very clear you are still having high levels of anxiety about these symptoms, despite the reassurance and thorough work-up at the ER. Hopefully the neurologist can further put you at ease, but I would REALLY recommend that you start addressing your anxiety. Even if your symptoms aren't 100% CAUSED by anxiety, you're sure having a lot worrying about this.
When you see the neuro, try to accept what he/she tells you, okay? And ask your PCP for a therapy referral. I think you'll feel a lot better if you can get this anxiety under control.
Good luck, let us know how the neuro appt goes!
