<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been experiencing joint pain, disturbance of memory, leg weakness, loss of sensation, and paresthesia. What do you think is wrong with me?  <response>: Based on your symptoms, its possible that you have Encephalitis, which is an inflammation of the brain that can cause those symptoms. I would recommend some tests to confirm the diagnosis and determine the best course of treatment.
