Back and leg pain

Ashley

Maybe someone on here can help me with this. For the past 5 days I've been having really bad back and leg pain. It starts in my back and spreads all down my leg. It feels like all of my leg muscles are tensing up at once. Its awfully painful and wakes me up. I have get off my side and stretch a bit to make it stop. Then i lay back down on my side and it comes back. Anyone ever have anything like this? What was it?
