### Patient: Doctor, I've been experiencing stiffness all over my body and my eyelid has been moving involuntarily. What could be the problem?
### Doctor: Based on your symptoms, it's possible that you have a tic disorder. Tics are sudden, repetitive, involuntary movements or sounds that some people make due to an urge they can't resist. Your stiffness could be related to the tic disorder as well. We should conduct some tests to confirm the diagnosis.
