Hi there,
The sensation you are experiencing is a symptom of something - what exactly is always the question. Have you brought this up to your doctor/neuro? If the doc does indeed label it lhermittes, he/she should work toward identifying the cause.
A little background on me is that I googled it when my doc 1st called mine lhermittes. I read the online definition and said to myself, this doc has no clue what he's talking about - this is not me. I've learned since then what those of us experience does not often meet the definition neatly.
In the meantime, please jot this down, avoid making it happen best you can. It's not typically painful, but it's uncomfortable. I avoid putting my head down to keep it at bay. Since yours is when you head is upright, you have to mention this to your doc and get a thorough exam.

Hi and thank you for answering. I had the same thought about how bending my neck forward could be relieving some pressure that may be causing the vibration.
I've been looking up cervical spondylosis and stenosis tonight and think I may be onto to something but have not found anything stating that vertigo could be a symptom of those.
Off to research some more! Thank you!
I think basically any movement of your neck that causes a change in sensation counts as L'Hermitte's. It sounds like you're relieving the pressure on your neck that's causing the vibration.
