leg/thigh pains.

I've recently been having some thigh pains. It's only when I'm laying down though. It hurts a lot and then stops hurting and then hurts again, it's kind of like a wave or pattern. I've read about something called sciatica or something, and I'm pretty sure it's that. But what I'm really here for, is a way to get it to stop hurting. I don't know anything even after looking it up several times.

Thanks-
Will.
