<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing weakness in my legs and hands, and even my fingers seem to be affected. Im also having some facial pain. What could be the cause of these symptoms?  <response>: Based on what youve described, its 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. Well need to do some tests to confirm this, but Ill refer you to a neurologist who can help diagnose and treat the condition.
