Lhermitte's Sign, sometimes called the Barber Chair phenomenon, is an electrical sensation that runs down the back and into the limbs, and is produced by bending the neck forward. The sign suggests a lesion of the dorsal columns of the cervical cord or of the caudal medulla. Although often considered a classic finding in multiple sclerosis, it can be caused by a number of conditions, including Behçet's disease,[1] trauma, radiation myelopathy,[2] vitamin B12 deficiency (subacute combined degeneration), and compression of the spinal cord in the neck from any cause such as cervical spondylosis, disc herniation, tumor, and Arnold-Chiari malformation.
Strictly speaking, the Barber Chair phenomenon is a symptom rather than a sign as it describes a subjective sensation rather than an objective finding. To add more confusion, it is not attributed to its discoverer.[3] It was first described by Marie and Chatelin in 1917.[4] Jean Lhermitte did not publish his first report until 1920.[5] However, in 1924 he did publish the seminal article on the subject which resulted in it becoming well known.[6]
Most modern editors prefer the non-possessive form for medical eponyms: Lhermitte sign.

It could also be the result of cessation or reduction of dosage of some drugs.
"The electric shock sensations reported with neck flexion seem identical to Lhermitte's sign, which appears with dysfunction of the posterior spinal cord. This suggests change at a neuronal level.[6]"

You could be pinching a nerve in your back. That's what causes the "funny bone" feeling" in your arm. Could be the same in your back, if it really bothers, ask to have an MRI done. If it is serious, as someone suggested, a specialist in nerve diseases should be consulted for a proper diagnosis.

Ask your doctor about an exercise routine. Regular exercise, such as walking three times a week, may reduce neuropathy pain, improve your muscle strength and help control blood sugar levels. Gentle routines such as yoga and tai chi might also help.

i have weird things like that too. i never noticed until i got generalized anxiety disorder.
i dont have what you are saying, but i will get it in my hands sometimes. And something even weirder, if i flex my left buttcheek, i get tingling in the back left of my head. its weird!
Oh, and i also notice its when i sleep for a long time. When i sleep for a long time, my lower back feels swollen or something and kind of hurts. That seems to have something to do with it too.

It sounds like you have a trapped nerve - a little like sciatica. It's unlikely to do you any harm, but anything like this is worth checking with your GP - always better to be safe than sorry.
