What are the symptoms of osteoarthritis?

Osteoarthritis symptoms include joint pain and discomfort, joint stiffness and tightness, crepitus (cracking or popping sounds) during joint movement, joint swelling and deformity, and reduced mobility. Progressive cartilage wear can gradually lead to various physical abnormalities. If you experience persistent severe joint pain, joint deformity, or difficulty walking, seek medical evaluation and treatment promptly.

1. Joint Pain and Discomfort: Pain typically worsens after activity and improves with rest. Cold exposure or excessive fatigue may further intensify the pain, which is localized to the affected joint and may impair basic daily activities such as walking or bending/extending the joint.

2. Joint Stiffness and Tightness: Stiffness commonly occurs upon waking in the morning or after prolonged periods of immobility. Usually, brief physical activity helps alleviate this stiffness; however, as the disease progresses, the duration of stiffness tends to increase.

3. Crepitus During Joint Movement: A grating or cracking sound may be heard during joint motion. Some crepitus occurs without associated pain. As cartilage wears down, joint surfaces become irregular, causing bone-on-bone friction that produces audible crepitus—indicating cartilage degeneration.

4. Joint Swelling and Deformity: Accumulation of fluid within the joint leads to localized swelling. Chronic disease progression may alter the joint’s original shape. Osteophyte formation (bony overgrowth) at the joint margins contributes to visible deformity, and palpation of the affected area may elicit tenderness.

5. Reduced Mobility: Joint pain and stiffness restrict the range of motion for flexion and extension. Discomfort becomes more pronounced during activities such as climbing stairs or lifting heavy objects, progressively diminishing limb endurance and interfering with daily living.

In daily life, protect your joints by avoiding cold, damp environments. Maintain a healthy weight to reduce joint loading, engage in low-impact exercises, and undergo regular joint-related examinations to slow the progression of cartilage wear.
