I'm so sorry to hear this has happened, it must be very distressing to see your ham like this.
If a ham is seen by the vet & given the appropriate medication straight away they can sometimes recover & continue to live comfortably for some time but as your ham's condition has already worsened & he can no longer walk or do things for himself I don't really think he has much chance of making a recovery, you need to take him to the vet & get their opinion, it is possible they may be able to help him but if he's in pain & has no quality of life now the kindest thing may be to help him on his way, it's a very hard choice to have to make I know but it may be for the best.
