The sciatic nerve thing you're mentioning...I've had that happen to me! About 4 years ago...it felt like I had a 4" knife stuck in the back of my leg & the pain went from my butt to my calf. :madvibe:
My right leg too! Maybe that's the only leg with that nerve? :dontknow:
I couldn't sit down at all, standing was the only time I was comfortable. Trying to drive was an excruciatingly painful experience. I went to a back cracker (chiropractor) for about a month before the pain started to subside.
My leg doesn't feel right to this day, although I can function normally now.
I hope your pin cushion experience works well for you. :thumbs:
