I keep getting on-and-off prickly, tingly sort of pins and needles feeling in parts of my left hand, and my fingers,, mostly on left hand but also on right hand sometimes. Its not really tingly coz i get that with hyperventilation (overbreathing) when im having a particularly bad timer with my anxiety, and it feels nothing like that...its more like pins and needles, they hurt sometimes too. Also, i got it in my top lip yesterday (to the left of my top lip) and it went numb for hours, then it went. I had it again today for about an hour then it went. The prickly sharp pins and needles in hands comes & goes throughout the day, I feel it sometimes when my hands are under my pillow at night. What is causing this? Im obviously thinking 'MS!!' coz i twitch/jerk alot too. Im 22.
