I would think so. I too am having the fleeting numbness feeling, I'll think my calf is numb and I'll quick run something light over it and I feel it normally! My knee cap is numb though, always numb (I recall injuring it a few years back so I am assuming that is why the knee cap is numb, but on the knee cap I feel NOTHING. I can pinch it, poke it, put something hot on it and I feel nothing.) but that fleeting weird numbness? I guess it's just a sensation. Whether it's a pinched nerve or anxiety I don't know. I opt for pinched nerve somewhere because when I take a Xanax I will still get that along with some tingling.
