Osteoarthritis (OA) is characterized by five primary symptoms that significantly impact the quality of life of those affected. First, joint pain, often aggravated by movement and alleviated with rest, is a telltale symptom, primarily impacting areas like the hands, knees, hips, and spine. Secondly, stiffness, particularly noted in the morning or after periods of inactivity, can limit mobility but typically eases with movement. Thirdly, a loss of flexibility may be observed, where the affected joint does not move through its full range of motion. Fourth, individuals may notice swelling around the joints, caused by a combination of soft tissue inflammation and excess joint fluid. Lastly, a distinctive symptom of OA is the presence of a crunching feeling or the sound of bone rubbing on bone, known as crepitus, which occurs due to the breakdown of cartilage in the joints.
