Not in my ear but there are times my body feels like there is a cell phone, set on vibrate, inside me.

I haven't experience the vibration in my ear like you have, but I often have vibrations in my body like I'll sit down in my chair and I'll feel like the chair is vibrating the strangest thing

Yes I have before. It wasn't intense. I think its like a muscle/nerve spasms. Not sure what to do to help with it though....

It's your tenants I believe

Thats definitely our nerves and nervous system misfiring I think. Its like a slight muscle spasm but deep in the nervs. I get them in my left arm leg and ear
