Thank you everyone for writing in this forum.
After reading the thread, I clearly have the symptoms of a periodic buzzing in the lower leg - 2 seconds soft vibration every 15 seconds. This started only 3days ago.

I am fortunate that my wife is a medical specialist - a family practitioner - who then specialised as a pediatrician (6 years experience) - who later specialised as a clinical geneticist (8 years exp.) - who finally specialised in pharmaceutical medicine (12 years exp.).

With her help I checked some cross references about l'Hermittes. Apparently, this condition can be caused entirely by inadequate support of the head and neck when sleeping and poor posture when sitting. I will be using additional and more supportive pillows to support my neck more from now on. Her comment to me was: "I recommend trying this for several days before any self diagnosis of MS!".

Hello Philster371 and welcome to NeuroTalk

I already like your wife

I have never heard of L'Hermittes being caused by poor posture/inadequate neck suppport...interesting.

I have L'Hermittes and have had it as a constant companion for 25 years. Mine is MS related. Although there can be other causes for L'Hermittes, when it is related to MS it is caused by Lesions on the cervical spine...I have numerous c-spine lesions.

When bending my head down I get vibrations/buzzing from mid-spine down, this can last seconds but I can repeat it everytime I bend my head.

If you are concerned about MS please feel free to ask questions and we will do our best to answer them.

Quick feedback after using one extra pillow last night with firm support in the base of the neck:

SYMPTOMS TOTALLY DISAPPEARED - and this after 3 days continuous buzzing.

I strongly recommend that you at least try this. Just because someone says you have Hermitte's because you seem to have the symptoms may not be true. Wikipedia even says:

Lhermitte's Sign, sometimes called the Barber Chair phenomenon, is an electrical sensation that runs down the back and into the limbs from involvement of the posterior columns, and is produced by bending the neck forward or backward.

Supporting my neck better removed the symptoms . . . it could work for you.

Hi and welcome! Phil, Clark, Morgan, karilann, godiva3ft and Tresa.

I have this too. It was part of Vertigo for me, also moving the head back and forth too fast in a store, looking around, I thought the floor was sinking. I had to hold on. The neck is involved, eyes too and ears.

FWIW:
They also say that when the jugulars have blockages, you should sleep elevated to allow some gravity to let the blood flow back down from the brain. The blood gets trapped in the head, causing pressure and perhaps iron build-up, they say.

Elevation has many benefits. Even for acid reflux. Keeps the acid down.

Keep your bed elevated at head level with those cups for the wheels, or put rubber under the head part of your mattress, or get a wedge to sleep on. Put it on top of your mattress and add a pillow if you like.

Back straight, head higher than the heart, and firm support.
JMO, and thoughts on this, which I have read about.

Thanks for the suggestion Philster371, but...I have MS.

No amount of neck support will change the fact I have L'Hermittes or symptoms of vibrations/buzzing. Those symptoms are caused by my Cervical Spine lesions courtesy of MS.

Since your symptoms disappeared due to better neck support you no longer have to worry about MS...CONGRATULATIONS!!!!!
