Please pray for my dad...his back is causing him trouble again

A week ago, my Dad was supposed to head up to Fort McMurray for work (hes doing sheet metal since there is no work in the oilpatch).I had learned a few days ago, he wasn't able to since his back started giving him problems again.His back has been on and off since he fell down a hole while on a rig site 10 years ago.The problem is in his lower back.I am praying for his recovery and hoping the physiotherapy helps.Hes on painkillers and this weekend he was barely even able to walk.They were supposed to come down to Red Deer to see me this weekend but couldn't because of my dad's back
