I really need some help here. I have a back problem and have a huge amount of medication to take every day, but I struggle to sleep at night because every time I lie down my hips feel like they're about to pop out of the socket and then my knees start hurting and my sciatica starts off. My sciatica is in my right leg but my left leg also hurts now. I've put 3 pillows between my knees, but this does not help. I literally wake up at night screaming with the pain. What is causing this and how do I stop it happening??
