Hi there, I am new here.
I started having these strange symptoms about 8 months ago and they are by no means regular. I may have it pop up a couple of times in one day then not again for months: hands start getting stiff with each thumb pulling inward towards my palm with tingling. Last night it lasted over a hour. It made it hard to type on the computer. There is never any pain.

More times than not, when it happens in my hands, it starts in my lips. They tingle and get stiff.

I am never anxious when this starts so I don't blame hyperventilation. Usually I am just going about life normal. I was sitting in my chair watching tv when it happened last night.

What could be going on?
