Ordinary aches and pains, such as muscle soreness after exercise or a long day, usually have an obvious trigger and ease within a day or two with rest. Arthritis pain, by contrast, tends to centre on the joints, persists or recurs over weeks, and is often accompanied by stiffness, reduced range of movement, and sometimes swelling or warmth.
The pattern offers clues. Osteoarthritis pain is typically worse with use and toward the end of the day, with short-lived morning stiffness. Inflammatory arthritis often brings prolonged morning stiffness (more than 30 to 60 minutes), symmetrical joint swelling, and general symptoms such as fatigue. Pain that wakes you at night or is associated with feeling unwell deserves attention.
See a doctor if joint pain lasts more than a couple of weeks, comes with swelling, warmth, or redness, limits your daily activities, or is accompanied by fatigue, fever, or weight loss. Early diagnosis matters, especially for inflammatory arthritis, where prompt treatment can protect the joints. Examination and tests are usually needed to confirm the cause.
