Pain in the right thumb finger

Pain near the thumb base can involve the thumb joint, while pain along the wrist side can involve tendons used to move the thumb. De Quervain's Tenosynovitis presents with pain on the thumb side of the wrist and may worsen during lifting, gripping, or thumb movement. A jammed joint may swell and limit movement. Clicking or locking can indicate a mechanical problem; tingling or numbness suggests that a nerve may also be involved.

Avoid forceful pinching, repetitive scrolling, tight gripping, and twisting until the pain settles. Keep movements gentle and comfortable, without forcing a swollen or stiff joint. A cold pack wrapped in cloth can be useful after a recent injury. A thumb support can reduce aggravating motion during short tasks, but it should not cause pressure, numbness, or colour change. Persistent pain deserves an examination.

Seek prompt care for a major injury, deformity, open wound, severe swelling, inability to move the thumb, or a cold, pale, or blue digit. Arrange assessment if pain continues, recurs, reduces pinch strength, or interferes with work and self-care. New weakness or spreading altered sensation should be reviewed promptly.

Is the pain coming from a tendon, joint, ligament, or nerve? Which movements should I avoid temporarily? Would a brace or hand therapy help? What improvement should I expect before increasing thumb use?
