I was reading a post which was talking about sciatic pain and that it shoots down from her butt cheek to the knee more pain in the night.. uncomfortable sleeping etc etc.. I would suggest trying to use an inversion machine. I had this problem for a few weeks and tried my friends inversion machine. it really hurt my feet hanging there so i could only do about 5minutes worth of hanging upside down.. but.. the pain went away and didnt get any more pain for about 2 years.. I have the pain again so I am going to visit my friend for a bit of relief.. hope it helps someone else to try it..
