Every night when I go to bed, I wake up around four or five with an extremely painful throbbing in my right shin. It always feels like it's deep in the muscle or the bone, and the only thing I can do to stop it is falling asleep, which is impossible to do with the pain. I've also found Vicodin works to stop it, but I've heard it can be addicting so I try and use it as little as possibee. I'm an extremely healthy person but had surgery for congenital scoliosis about three years ago. Cound these be related?
