I have described it as Freddy Kruger ripping through my calf. Then there's the Jolly Green Giant squeezing my ankle/leg. The crazy "Oh my Gawd! Is there wet quicksand in my sock???" And shooting hot/cold mixed together...like there was a fire lit to my leg and someone puts ice on it. When my 'pins & needles' get bad, I say there's leprechauns in there stabbing me.
I love pain/sensation descriptors! They're my fave
