Osteoarthritis occurs when the cartilage of a joint erodes (breaks down). Bones begin to rub against each other, causing pain and difficulty moving the joint. Osteoarthritis also can affect nearby bones, which can become enlarged in places. These enlargements are called bone spurs or osteophytes.
Here are some common signs of osteoarthritis that may help you to identify and better describe your pain to your doctor: 1  Pain that aches deep into the joint. 2  Pain that feels better with rest. 3  Pain that isn't noticeable in the morning, but gets worse throughout the day. 4  Pain that radiates into your buttocks, thighs, or groin.
