Joint pain is a symptom. Arthritis refers to diagnosed joint diseases (for example osteoarthritis or rheumatoid arthritis) with specific clinical criteria. Many people have temporary joint pain without meeting criteria for a chronic arthritis diagnosis.

Osteoarthritis vs inflammatory arthritis (high level)

Osteoarthritis often involves activity-related pain and shorter morning stiffness. Inflammatory forms may involve longer morning stiffness, swelling, and systemic features. Only a clinician can differentiate using history, exam, and sometimes labs or imaging (see NIAMS consumer pages on OA and RA).

Other causes of joint pain—bursitis, tendon issues, infection, crystal arthritis (gout/pseudogout), or referred pain—can look similar to arthritis to a non-clinician.

Why self-labeling is risky

Mislabeling can delay care for infection, crystal arthritis, or autoimmune disease. If symptoms persist, escalate rather than self-treat based on search results.
