You asked: "Can Lhermitte's sign exhibit itself in many different ways?"
The answer to your question is a huge YES.
I won't write in detail all the weird manifestations of Lhermitte's that I've experienced (I've done that previously); suffice it to say that according to MANY people's experiences that I've read about, not to mention my own, Lhermitte's can manifest as many different sensations (shocking, buzzing, vibrating, tensing, paresthesias of various sorts) and in many different places (usually from the neck down, but occasionally up, and sometimes just in particular spots in the lower body or hands) and with various movements (including bending or turning the head, bumping over something on a bicycle, taking a deep breath).
I have not heard of someone having the sensation only after returning the head to normal position, but I suppose that's possible, too! I'm sure that not all neuros would label this as Lhermitte's, but the mechanism must be the same or very similar--movement causing some irritation of the damaged nerve. That's my non-expert "opinion." :)

I did end up looking under the Health Pages some info on Lhermitte's manifestation.
I have been having these chills or "GOOSEBUMP" sensations for a lot longer than I originally thought, although now I do notice it a lot of the time when sitting in front of my computer working my job as a medical transcriptionist. My head/neck is always adjusted in a slightly downward position looking at the screen and not straight forward.
When I go back to the neuro in 2 weeks, I am not sure if it is worth mentioning to him or not; he will probably just shrug it off anyway.
thought I'd add my own question to the mix because lately I have been having what I can only describe as 'electric shocks' from my hands when I open them, go to let go of something or try and pick something up.
I seem to be highly charged or something because I can't even press a lift button without getting a shock and the other day I managed to give my cat an electric shock when I went to stroke him - poor thing!
Is the hand thing another way of experiencing the L'H or is it different and I'm just weird? LOL
Wishing everyone a happy/healthy weekend
My feet tingle and I have a cold rush from my neck down my arms and then my arms get very heavy.
I'm also a transcriptionist but I keep my monitor a littler higher so I don't look down. I actually work off two computers, so maybe moving back and forth between the two keep me from getting locked into one position for too long.
I hope you are doing better today and your hands are not as sluggish. I know what you mean about the monitor, I am doing the same thing or adjusting the text on page so that it is higher.
My biggest problem lately has been with "editing" voice recognition reports, going along line by line fixing reports because of the old vision thing.
From what I've gathered is Lhermitte's experiences itself in many different ways. In the Health Pages at the top right of the page, there is something on this that explains it, which I found very helpful.
