<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Im having a hard time speaking fluently. I feel like my tongue is not working properly.  <response>: Based on your symptoms, it could be a sign of Guillain Barre Syndrome, a rare condition where your immune system mistakenly attacks your nerves, resulting in muscle weakness and difficulty speaking. We need to run some tests to confirm the diagnosis.
