Okay, first off, you have to breathe. I go numb and tingly in my extremities all the time, especially when my anxiety is high. You don't have to be having a panic attack to have high anxiety...sometimes I wake up and I'm more tense and edgy for no reason at all. Seems I breathe very fast and shallow those days, especially when doing things that require concentration. (ie. driving, reading, paying bills) I also tend to hold my breath when I'm like this. The two most common places I lose feeling is in my hands and feet, although occasionally my face and neck will go numb. Weakness isn't a sensory feeling, like a numbness or tingling, weakness is obvious. If you were having foot weakness you wouldn't be able to move your foot properly between pedals. That would be a true weakness. What you are experiencing, whatever the cause, is a sensory issue...not a weakness issue.Frances
