What is paresthesia?

ANSWER

If you fall asleep with your arm pinned under you or keep your legs crossed too long, chances are, you've had a "pins and needles" feeling in your limbs, fingers, or feet.

That prickling, burning, tingling, numb, itching, or "skin crawling" feeling is called paresthesia. While it may seem weird, it's usually painless and harmless.
