Hello John,
In my opinion it is time (past time) that you seek advice from other doctors. In fact, advice from 2-3 of the very best spinal surgeons in your area.
AND by all means DON'T try to be your own docrtor. Yes, exercises can help, but they MUST be under the direction and guidance of a very well qualified physical therapist. AND you must do those exercises at the PT center so that your therapist can make sure you are doing the excercises correctly.
I am not a doctor, but until you get the advice from the spinal surgeons I would suggest that you NOT jog. You may just be doing more damage to your spine.
