I too experience pain in my "kidney are" up
. Throughout the week I get minimal sleep; five hours maximum, and waking
with NO pain, but when the weekend comes, and I am sleeping more than that is when I experience this horrible pain. So, I know for a fact that the pain is directly related to sleep (for me). I first went to my MD, and was told that it is muskuloskeletal, and that Motrin should help. No dice.
