hi Lisa,

Well`I have very similar zaps and yows in my right wrist hand/wrist/arm, worse in my hand; this isn't my RSD arm, that's the left one. I was diagnosed in the Spring with Spinal Stenosis (pinched spinal cord) and Cervical Spondylosis (arthritic growths on C4-C6, so pinched nerves too) which is worse on my right side (I'm right handed, think it's always worse on whichever side you favour). They found it using MRI.

Your description of numbness combined with extreme sensitivity of the electrical zappy kind is absolutely identical to me, yes, it's so strange, plus the pressing which produces kind of painful electric shocks.

They haven't said what they think the cause is exactly, (RSD, RSI, SS or CS) but it's not the same as the RSD arm...

I've got a doc appt next week, I'll let you know if they come up with anything

Just wanted to throw in my $0.2 worth!
all the best
