Joints are the parts of your body where your bones meet. Joints allow the bones of your skeleton to move. Joints include:
- shoulders
- hips
- elbows
- knees
Joint pain refers to discomfort, aches, and soreness in any of the body’s joints. Joint pain is a common complaint. It doesn’t typically require a hospital visit.
Sometimes, joint pain is the result of an illness or injury. Arthritis is also a common cause of joint pain. However, it can also be due to other conditions or factors.
What causes joint pain?
Arthritis
One of the most common causes of joint pain is arthritis. The two main forms of arthritis are osteoarthritis (OA) and rheumatoid arthritis (RA).
According to the American College of Rheumatology, OA is most common in adults over age 40. It progresses slowly and tends to affect commonly used joints like the:
- wrists
- hands
- hips
- knees
Joint pain due to OA results from a breakdown of the cartilage that serves as a cushion and shock absorber for the joints.
