I'm sorry to hear this. The only thing that I can suggest is to call your vet and let him/her know what's going on. Maybe your vet will have some good ideas. I know that by giving an animal pain medications, they sometimes feel too good so they won't rest and let themselves heal. Maybe you should try to give him fewer pain meds. I think I only gave my RB Starr his pain meds at night when he was more likely to sleep Good luck.
