Stiff, swollen and painful middle finger: what to know

Swelling around a knuckle can limit bending, while pain along the palm side may point toward a catching tendon. A finger that gradually draws toward the palm can occur with Dupuytren's Contracture. Aching and bony enlargement may fit Hand Osteoarthritis, while warmth, several tender joints or prolonged morning stiffness can occur with Rheumatoid Arthritis. Trigger Finger may cause clicking, catching or a finger that temporarily locks. These patterns do not establish a diagnosis on their own.

Note whether one joint or the whole finger is swollen, whether symptoms followed a knock, and whether numbness, redness or fever is present. A clinician may examine movement, tendon glide, sensation and circulation.

Reduce activities that forcefully grip, pinch or repeatedly flex the middle finger. Keep the hand gently moving within a comfortable range rather than holding it completely still for long periods. Elevating the hand can help with swelling. A wrapped cold pack may soothe a recent flare; protect the skin and stop if it increases pain or numbness. Do not force a locked finger straight. A pharmacist or clinician can help you choose pain relief safely, especially if you have other conditions or take regular medicines.

Arrange prompt medical assessment if the finger is markedly red, hot, rapidly enlarging, severely painful, or difficult to move after an injury. Seek urgent care if it looks deformed, becomes pale or blue, loses feeling, or you cannot actively bend or straighten it. Fever with a hot swollen finger also needs prompt attention. If symptoms persist, recur, or interfere with work, sleep or grip, book an examination to identify the cause.

Ask which structure seems affected, whether an injury or inflammatory condition needs checking, and which movements should be limited. Ask whether a splint, hand therapy or imaging is appropriate, and what changes should prompt earlier review.
