I am at day 17, and even a few days make a big difference. Not being a back sleeper, I have differrent problems at night (yes, I have pain, and have yet to sleep more than 3 hours at a stretch), but I suspect that the tingling in the good leg is caused by pressure on that sciatic nerve. I was told in the hospital not to use a pillow cross-wise when on my back, but use it lengthwise under the leg to cradle it. Perhaps you could try to put a very small and low pillow crosswise under your good leg to balance your hip angles. Can’t hurt to try! Otherwise, try looking toward the future (and remember how bad it was that made you go for this surgery). I try to do that when I get discouraged.
