Funny about the knitting needle reference.  It's the same term I use and have been getting jabs since feeling first returned to my leg 5 years ago.  Big toe, foot, ankle, (both legs) and  knee and thigh have been it's favorite spots but my calf is a new one.  
Pretty sure I was slightly negative and can't help but think it's a cause and effect though by now, the needles have slowed considerably.  Wish they would stop as I'm still unsure which is appropriate, hitting the ceiling or the floor- though the floor has the advantage of being easier

.  PM says it's nerves waking up- I say they're aggravated because I did something stupid!
D... ouch!
