Bit concerned

This may seem weird but does anyone else feel like there back is vibrating inside even tho it isn’t ??? Is this a sign of anxiety 

I get vibration feelings in my legs hands feet it comes and goes.

I get it in my back it’s weird 

I get that feeling on the top of my head. & last night it happened in my leg. 

Mines in my back and sometimes legs 

It could be a psychosomatic symptom of anxiety?  

When I'm anxious, recently I feel some aching in my shoulders.  I wonder if anyone else feels this?

Best,

Jonathan
