You really do have some issues Billy. It sounds like the doc. isn't sure what is causing all your symptoms, just some of them. Very complicated DX. Have you gone as far as a teaching hospital? Sometimes the DX from places like this are more conclusive. It also didn't say that surgery was recommended. The drop foot is neurological, and so is less nerve input to the tibial and foot. PN can cause numbness like that too.
I really wish I knew more. Most of the information I get is from the MD Web site. I am sorry you are having to deal with all this. what kind of pain level do you have? Are you on any type of medications? I am here to listen anytime. Good that you have gotten more than one opinion. Let me know how you are doing as things go along. Jo*Mar one of our moderators, knows quite a bit more than I do, and may be better than I am with the terminology. Our best at MRI's is out sick. I miss her guidance. I try to walk in her footsteps and learn all I can.
Keep in touch Billy, I do care. ginnie
