QNS, I don't get much sleep at night either, no matter which way the leg lays it hurts.. I have a pillow for under my knee but that doesn't seem to help either...I do use the TENS unit alot...I got mine from the chiropractor..now they sell them online on Ebay very reasonable...that helps alot...it short circuts the pain...helps with swelling also..I have to get more pads.....Have to leave now for an appt...later..H.
