My lower back is junk

I'm there now. Have a herniated disc in my lower spine and pain in my kidney area and lower back. Can't stand still very long or it hurts like crazy. Can walk maybe a hundred yards and then need something to lean on. Dr. said it may be the disc or just muscular ( or lack thereof ) that is causing the problem. Sent me to PT and the therapist agreed it may not be disc causing the problem. I just started PT, and these exercises he has me do, so will see. Back pain is really taking away any enjoyment I was looking forward to after the miserable winter. Hope you get some relief.
