Tizz,
It was certainly a "what the hell do I have wrong now" moment when L'Hermitte's Syndrome arrived a few weeks back. My doctor did confirm it was that. Surprisingly, i notice soaking in baths helps it a lot. I had to do that for another issue, but it's knocking out to birds with one stone.
I also noticed the days I sit in the car for extended periods of time, and days that I am extremely stressed, my neck/shoulders tense up and that feeling gets worse. The muscle relaxers (Flexerol or Anna Trampoline - can never remember the right spelling, but that's how it sounds) help with that, too.
Glad we only have a few months with this one. It's one I'm certainly ready to pass on!
