This idea may not pertain to many of you, but I can now sit a few more minutes at a time using a small footstool. Elevating my worst leg 4-5" provides a little relief. Now have three, one in each car and one at home. Made by Econo HIgh, Inc., about $25 on US Amazon.com. Also helpful for blood clots, short legs, all sorts of nerve pains. Folds small enough to fit in purse--so I can also carry seat cushion. Have to keep sense of humor about needing all these gadgets.
