This has happened me a few times now but last night it was particularly painful so I thought I'd see if any of you had any ideas? When I'm sleeping on my left side (always with a small pillow between my knees) I wake up and my left leg is completely dead and sore from the outer hip right down to my calf. I can still feel where it was sore in the night now. I know it's not like SPD as I have this slightly in my right hip and it's a different kind of pain. Anyone any ideas?
