Jack is absolutely correct in stating that you need to do the exercises. The longer you delay, the longer it will take to fully recover and get your strength back in the spinal area where you had surgery.
Jack, hang in there. It may take you a while, but you will walk again. I have that much faith in the power of exercising, healing and determination.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
