Sounds to me like you are experiencing spondyloarthropathy [SpA] that is associated with Crohn's. The symptoms of stiffness occuring after inactivity and easing when you move is exactly what happens to me and I was initially diagnosed with SpA. If you are experiencing pain in the very lower back, about
where the dimples are above the buttocks, it is likely your SI joints are the source of the problem. A rheumatologist can be very helpful at evaluating and treating this type of problem.
