### Patient: Doctor, I've been having a lot of pain in my foot and toes, and my hands and fingers are swelling. On top of that, my legs feel weak and heavy. What could be causing all of these symptoms? 
### Doctor: These symptoms could be a result of a condition called Syringomyelia, which is a rare disorder, in which a fluid-filled cyst forms within your spinal cord. This cyst can cause nerve damage and a wide range of symptoms, including those you've mentioned.
