<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi doctor, Ive had some severe pain in my back and lower spine lately. I think I might be suffering from spondylitis.  <response>: I see. In order to diagnose spondylitis, we will need to run a few medical tests. The first one is a plain x-ray or MRI to get a clearer picture of your spines condition. We may also need to perform some physical therapy exercises, manipulation, or other non-OR or closed therapeutic nervous system procedures. Additionally, we may need to consider inserting a catheter or spinal stimulator and injection into your spinal canal or other therapeutic procedures to manage your pain.
