### Patient: Doctor, I have been experiencing elbow weakness and low back pain. Do you know what might be causing it?
### Doctor: Yes, based on your symptoms, it's possible that you have Zenker diverticulum. This is a condition where there is a pouch that forms in the wall of the throat, which can sometimes cause symptoms like difficulty swallowing, regurgitation, and even pain in the neck, shoulders, or back. Would you like to schedule further tests to confirm the diagnosis?
