Pain in the Palm Between the Thumb and Index Finger

This web space helps the thumb pinch, spread, and grip. Repeated gripping, phone use, lifting, or a small strain can make it sore. Pain that travels toward the thumb side of the wrist, especially with grasping or lifting, can be a presentation of De Quervain's Tenosynovitis. A fall or forceful bend may injure a ligament, joint, or bone. Numbness, tingling, weakness, or visible swelling adds useful information for a clinical examination.

Rest the hand from forceful pinching, jar opening, prolonged writing, and heavy gripping for a short period. Keep the fingers and thumb moving gently within a comfortable range so the hand does not become stiff. A cold pack wrapped in cloth may calm soreness after recent overuse; stop if skin becomes painful or numb. Do not tightly strap the thumb without guidance. If symptoms continue, a clinician or hand therapist can check movement, strength, and tendon loading.

Seek prompt care after a fall or blow if the thumb looks crooked, swelling is marked, movement is very limited, or the hand feels numb or unusually cold. Arrange an appointment when pain persists, interferes with gripping, or repeatedly returns during ordinary tasks. Sudden loss of thumb strength or spreading redness needs urgent assessment. Bring details about the activity that started the pain and any change in sensation.

Which structure is tender: the thumb joint, tendon, muscle, or ligament? Should I use a splint? What hand movements should I modify, and when can I resume stronger gripping?
