An osteoarthritis diagnosis explains why a joint that used to work fine now aches, stiffens, and complains. This is the calm, plain-English companion for what comes next. It explains why cartilage wears down and why exercise, not rest, is the real first-line treatment, the difference between osteoarthritis and rheumatoid arthritis, medication options and their real risks, and when surgery actually makes sense. It covers everyday life with a joint that doesn't cooperate. No jargon. No fear. No filler. Just what you actually need, in the order you need it, with clear tables, checklists, and the exact questions to bring to your next appointment.
