### Patient: Doctor, I have been experiencing an ache all over my body and I've been having joint pain as well. What could be the reason for this?
### Doctor: Based on your symptoms, it seems like you may be suffering from ankylosing spondylitis, a form of arthritis that affects the spine and other joints. It usually starts as stiffness and pain in the lower back and can spread to other areas of the body like the hips and shoulders.
