I have trouble describing the sensory feelings my feet go through sometimes. I have had numb, tingly, feeling like not there...

but, I have this weird sensation sometimes that is very odd and hard to describe....like my foot or just one or two toes is almost growing. It is kinda tingly but not in the usual way, more like a little vibration and like it is getting bigger or there is something being put on it.

what is this?

and do you ever wake up in the middle of the night with your hand or arm or something asleep? like it wakes you up?

Is this normal?
