I pinched the siatic(sciatic) nerve around my hip, and have quite a lot of pain all the way from my hip down to my foot.
The best thing I have found so far is to lie flat with my legs raised on pillows (almost in a sitting position, except laying down). I then slip a cushion under my lower back which suspends my butt a bit, and try to hold for 5-10 min. It hurts the back while doing it, but that quickly disappears, and the leg pain goes away for 1-3 hours.
Some more discusion about it.
