<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, Ive been having headaches and weakness in my legs, do you know what could be causing this?  <response>: Based on your symptoms, it sounds like you could be suffering from Syringomyelia, which is a condition where a cyst forms in the spinal cord, causing pain and weakness in various parts of the body. I would like to run some tests to confirm this diagnosis.
