### Patient: Doctor, I've been experiencing weakness in my legs and hands, and even my fingers seem to be affected. I'm also having some facial pain. What could be the cause of these symptoms?
### Doctor: Based on what you've described, it's possible that you have chronic inflammatory demyelinating polyneuropathy (CIDP), which is a condition that affects the nerves and can lead to weakness in the limbs, as well as pain or numbness. We'll need to do some tests to confirm this, but I'll refer you to a neurologist who can help diagnose and treat the condition.
