What should you know about stiff index finger pain?

Pain at the knuckle may point toward a joint problem, while catching or locking as the finger bends can occur with Trigger Finger. Hand Osteoarthritis may cause aching, reduced grip, and stiffness after rest. Rheumatoid Arthritis can affect several joints and may bring swelling or prolonged morning stiffness. Dupuytren's Contracture usually creates tightening in the palm that gradually pulls fingers toward it; it is different from simple soreness. Read about [Finger Stiffness](/symptoms/finger-stiffness/) for a broader symptom guide. The location, timing, swelling, and hand function help a clinician narrow the possibilities.

Reduce gripping, pinching, and repetitive tapping for a while, but keep the finger moving gently if movement is comfortable. Warm water may ease stiffness before light motion; a cool pack wrapped in cloth may help after activity if the finger feels irritated. Do not force a locked finger straight or tightly squeeze a ball. A clinician or hand therapist can assess tendon glide, joint motion, strength, and the need for a splint.

Get prompt care after a significant injury, if the finger is crooked, numb, blue, rapidly swelling, or impossible to move. Seek urgent advice for redness and warmth with fever. Arrange an assessment if pain persists, catching increases, swelling affects other joints, or grip and everyday tasks are becoming difficult.

Ask whether the pain is centred in a joint, tendon, or palm; whether a splint or hand therapy could help; and what movements should be limited. Mention previous injuries, psoriasis, and symptoms in other joints.
