Pain in the Thumb Radiating Up the Arm

An irritated tendon can cause pain near the thumb side of the wrist, especially after gripping, lifting, or repeated hand use. De Quervain's Tenosynovitis is one condition that can present with pain around the thumb side of the wrist; see the condition guide for more detail.

Pain that extends farther up the forearm, or comes with tingling, numbness, burning, or reduced grip, can point toward nerve irritation. A recent fall, twist, or direct blow raises concern for an injury. The pattern, strength, sensation, and movement of your hand help a clinician separate these possibilities.

Reduce activities that reproduce the pain, such as forceful gripping or repeated thumb movement, while keeping the fingers gently mobile. Support the wrist and thumb in a neutral position if that feels more comfortable, and use a wrapped cold pack for short periods after aggravating activity.

Arrange a clinical assessment if the pain persists, keeps returning, or limits work, sleep, or normal hand use. A clinician may examine the thumb, wrist, elbow, and neck rather than focusing on the painful spot alone.

Seek urgent care after a significant injury, or if the hand becomes suddenly weak, numb, cold, pale, or blue. Prompt assessment is also needed for marked swelling, deformity, spreading redness, fever, or pain that is rapidly worsening.

Ask which structure appears to be causing the radiating pain, whether sensation and grip strength are affected, and which movements should be limited. You can also ask whether a thumb or wrist support, physiotherapy, or further testing is appropriate.
