What should you know about finger knuckle stiffness?

The large knuckles where the fingers meet the hand can become stiff after a knock, repetitive gripping, or prolonged rest. Hand Osteoarthritis may cause pain and reduced motion in finger joints. Rheumatoid Arthritis can present with swollen, tender knuckles and difficulty making a fist. Trigger Finger usually affects smooth tendon movement, causing catching or locking, while Dupuytren's Contracture can gradually limit finger straightening through tissue in the palm.

Compare both hands and look for warmth, swelling, tenderness, a change in alignment, or reduced grip. These observations are more useful than judging the cause from stiffness alone.

Move the knuckles slowly through comfortable flexion and extension several times during the day. Warm the hand before movement if it feels tight, and cool it briefly after activity if swelling follows use. Avoid forceful squeezing and prolonged pressure on the knuckles. If a recent injury caused the problem, protect the hand and arrange assessment rather than testing it repeatedly.

Arrange review if stiffness lasts, progresses, affects several knuckles, or limits writing, dressing, or gripping. Seek urgent care for a deformed finger, inability to move it after injury, numbness, unusual coldness or colour, or a hot red joint with severe pain or fever.

Ask which structure is limiting movement, whether hand therapy or a temporary support would help, and how much activity is appropriate. Ask what symptoms would mean you should return sooner.
