DH was told last year that he has arthritis in his knee joints and that if they operated it would make the arthritis come on faster, anyway he chose not to have the operation, but now 1 year on, he is in contant pain, very swollen knee joints, and can barely walk. what should he do? I have told him to get to the doctors and get some strong painkillers, but he said that when we move he was going to go back to work, now that won't happen because of the arthritis, so is there any benifits he can claim for arthritis??
