"Rheumatism"
That's what a lot of our parents and grandparents probably called it.
We call it arthritis, The "arth-" comes from the Greek word for "joint" and the "-itis" is a suffix meaning "inflammation" or "infection".
When we talk of arthritis we are mostly discussing osteoarthritis (OA) which is a wearing down of the articular cartilage where bones articulate (join together). This happens for many reasons, mainly aging, repetitive (or sometimes acute) injuries, overuse and occasionally other disorders. It is very different from rheumotoid arthritis, septic (infectious) arthritis and several (often systemic) autoimmune diseases such as Lupus. When cartilage is damaged too much there can be areas where bones rub against each other ("bone on bone") which is quite painful.
Although OA can be inflammatory it is not necessarily so. Inflammation may be a result as well as a cause. If I had been in charge of naming this condition, I would have called it "arthrosis" as "-osis" is a suffix that means "an abnormal condition of -". Generally, OA is related to aging and how we have used - or abused - our joints. I would wager that most, if not all, septuagenarians have OA that could be found on XRays somewhere in their bodies.
Yes, aging beats the alternative, but it does not come easily!
