<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing low back pain, headache, and problems with movement lately. What do you think could be causing this?  <response>: Based on your symptoms, it seems like you might be suffering from spinal stenosis. It is a condition in which the spinal canal narrows and puts pressure on the nerves, causing pain and difficulty in movement. I would suggest some tests to confirm the diagnosis and then discuss treatment options.
