I have only felt it in my arms and hands maybe once or twice. I do feel it in my hips and lets almost every night, however. It doesn't matter which side I lay on, left or right, usually about 2-3 minutes after I have been laying on my side, my hip starts to tingle and go numb, and it spreads right down my leg. It's so annoying, and has been keeping me up at night!!
I'm not sure of what it means, but I hope it starts to get better for you. I completely understand how annoying it is!
