Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage on the ends of your bones wears down over time. Although osteoarthritis can damage any joint in your body, the disorder most commonly affects joints in your hands, knees, hips and spine.
Osteoarthritis symptoms often develop slowly and worsen over time. Signs and symptoms of osteoarthritis include:
- Pain. Your joint may hurt during or after movement.
- Tenderness. Your joint may feel tender when you apply light pressure to it.
- Stiffness. Joint stiffness may be most noticeable when you wake up in the morning or after a period of inactivity.
- Loss of flexibility. You may not be able to move your joint through its full range of motion.
- Grating sensation. You may hear or feel a grating sensation when you use the joint.
- Bone spurs. These extra bits of bone, which feel like hard lumps, may form around the affected joint.
Osteoarthritis symptoms can usually be effectively managed, although the underlying process cannot be reversed. Staying active, maintaining a healthy weight and other treatments may slow progression of the disease and help improve pain and joint function.
