What should you know about knuckle joint stiffness?

Stiffness may be worse after rest, in the morning, after repeated hand use, or following an injury. Swelling, tenderness, warmth, clicking, or difficulty making a fist can provide useful clues. Osteoarthritis may affect joints through wear-related changes, while rheumatoid arthritis can cause inflammatory swelling and stiffness. A clinician may also consider tendon problems, a previous fracture, infection, or another inflammatory condition.

The symptom itself does not identify one diagnosis. A hand examination can compare both sides, assess grip and movement, and decide whether imaging or blood tests are useful.

Keep the fingers gently moving within a comfortable range rather than forcing a painful stretch. Warm water may ease stiffness for some people; protect the hand from tasks that repeatedly trigger swelling. Record which joints are affected, when stiffness occurs, and whether symptoms are present on both hands. Physiotherapy can address movement, strength, and joint protection, while hydrotherapy may offer a supported setting for exercise.

Arrange medical assessment if stiffness persists, limits work or dressing, keeps returning, or comes with visible swelling. Seek urgent care for a suddenly hot and swollen joint, severe pain after an injury, a crooked finger, loss of sensation, or a finger that becomes pale or blue. Fever with a painful swollen joint also needs prompt attention.

Which knuckle or nearby joint is involved? Does the pattern suggest arthritis, tendon irritation, or an old injury? Should I use heat, a splint, exercises, or medication? Which changes mean I should return sooner?
