What is the most common symptom of osteoarthritis?

Joint stiffness is indeed the most common symptom of osteoarthritis. This stiffness typically occurs after periods of inactivity or upon waking in the morning and may improve with movement throughout the day. In osteoarthritis, the cartilage that cushions the bones gradually deteriorates, leading to an increase in friction between the bones, which can contribute to a sensation of stiffness.

While other symptoms such as swelling and redness can occur in osteoarthritis, they are not as prevalent as stiffness. Increased range of motion is unlikely, as osteoarthritis tends to restrict movement rather than enhance it. Numbness in the joints generally does not characterize osteoarthritis; it is more commonly associated with nerve issues or other conditions. Understanding these distinctions is crucial for recognizing and managing osteoarthritis effectively.
