Hello bny806,
Sounds like L'hermittes to me
I have had Lhermittes for 29 years. What I experience is vibrations/buzzing from the waist down whenever I look down. I have never had pain associated with this symptom but I know some do experience pain with Lhermittes.
Lhermittes is not unique to MS, there can be other causes for this symptom. However, when you have MS and Lhermittes it is caused by a lesion(s) on the cervical spine.
There is no treatment for Lhermittes other than immobilizing the neck (collar), although not practical or permanent. If you are experiencing pain with Lhermittes then that part can be treated with medication, talk to your Neurologist.
