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.
In some cases, bone spurs on the spine can pinch a nerve root â causing pain, weakness or numbness. If you have osteoarthritis, your doctor will work with you to develop a treatment and pain management plan, which may include exercise, medications and measures to protect your joints. Your doctor may also refer you to a rheumatologist, physical therapist or orthopedic surgeon.
