what causes bump on wrist below thumb
De Quervain's may cause pain when you twist your wrist. You might also have pain if you grab something between your thumb and fingers. Many people hear a funny sound like a squeak, crackle, snap, or creak when they move the wrist or thumb. The bottom of the thumb or the side of the wrist might also be sore or swollen. This can make it hard to move your thumb or wrist. The back of the thumb and index finger may also feel numb. Sometimes de Quervain's can cause a small bump on the thumb side of the wrist. If you don't get treatment, the pain can spread up your forearm or down into your thumb.
