I'm female, 26, 5'2'' 154, I woke up from a nap about an hour or two ago and my left foot, on the top right has this... weird sensation. It's kind of like a vibration, it hasn't gotten any better or worse, both feet are the same color, I havent' had shoes on since I got up, have walked around the house a bit. There is NO pain, and I've stretched/popped my back to try and pop anything that might be putting pressure on a nerve, as I do have issues with that, it didn't help but there's no guarantee I got everything popped back into place. I've tried stretching out legs and sitting at a chair both. When sitting at a chair my left leg feels a little colder, a tiny bit of tingly sensation, doesn't appear to be getting any worse or better, unless it's just slowly worsening and just got to the colder tingly leg after I switched from laying to sitting.
