Hello, I Am Writing Regarding My Fiance. He Is A

Hello, I am writing regarding my fiance. He is a severe alcoholic. The last I would say 3 months he has been having severe problems with his feet and legs and now recently his back. His feet, toes and ankles are very swollen, bruised and don't get any better with rest. He also says they are tingling and numb all the time. The last week however his back has been hurting very badly and he is sleeping all of the time. I can't get him to go to the doctor what are your suggestions on what it could be? Also yesterday we notcied he was leaning up against the wall and it left and indent in his skin as well as making it red that didn't go away right away. Also he said that he hurts when he leans on things. I will send pics of what his feet look like
