Gosh, I'm glad someone else has these - I thought I was going nuts! I get these in my rear end - the vibrations ~ and I always get the electric shocks, but I've had those for years.

I have spinal problems, and the electric shocks I'm familiar with, but these vibrations are new - "silent migraines" in the butt??? LOL

My central nervous system is inflamed now because I've had chronic pain for 25 years in the spine ~ and when I first felt these vibrations, I thought we were having a mini earthquake! LOL Well, it COULD happen!

Have a great day. Hugs, Lee
