I get that too and it's very annoying, but I try to ignore it. It can be a couple of toes, part of my foot, an arm, pretty much anywhere. It's just anxiety because as you stated, it's there then it's not and even thinking about it can cause it sometimes.

Yes, I have read that it is a symptom of anxiety. I can literally call up the feeling in whatever extremety I choose and it will appear within seconds. Try it. It's crazy.... Having said that, a physician once told me that ANY sympton can be caused by anxiety but I do believe the pins and needles/tingly sensation is one of the more common ones. I hope this makes you feel a bit better!

Omg ive been dealing with this for weeks my left foot just starts going numb then near my ankle feels like ive got that tickly feeling like its waking up after being dead ive also been getting it on my arm and hand im freaking out about it coz after reading doctor google im pretty sure i have ms or some other serioys illness im scared to death.im realy working up the courage to call the doctors first thing monday morning but im petrified x

Does this sound like what you have been getting x

My symptom is weird because it doesn't feel like tingly per say or even numb, it literally feels like for example your foot falls asleep and when it starts to wake up yes you get the tingly feeling but also the weird painful sensation in your muscle maybe, but not at the height of that feeling when its almost done waking up, so it's not "pain" but it's that feeling just not as intense. I dont seem to feel it at night in bed or in the morning waking up but once I get out of bed to start the day there it is! Idk if it's because I'm thinking and dwelling on it before I even get up or if it's really something...idk I just wish it would stop and I knew 100% it was anxiety!
