What could be the cause of a painful lump near the wrist area? (photo)

The arrow in the picture points to the base of the 2nd metacarpal or 2nd carpometacarpal joint on the dorsum of the left hand. At this location, the most common causes of a painful lump or bump are:

1. 2nd metacarpal bossing
2. Synovitis of the insertion of the extensor carpi radialis longus tendon
3. Synovitis of the extensor indicis communis or propius tendon to the index finger

A hand & wrist specialist will be able to clinch the diagnosis with a detailed clinical examination and imaging modalities such as X-rays, ultrasound or MRI scans. Early treatment will prevent the problem from becoming a chronic one, which may be trickier to treat.

Lumps can be from different causes:

1. Skin

2. Soft tissue

3. Bones

4. Joints

Common causes around the wrist are ganglions and these can cause pain at times. It maybe worth visiting a MSK/Sports Physician for an assessment and sameday ultrasound assessment before deciding on further treatment.

Hope this helps.

Unfortunately, the swelling is not very obvious from the clinical photograph. I think for a proper diagnosis, you should get this checked out by your doctor.

Some comon causes of swelling around the wrist include a ganglion. But you will require a close examination to make the diagnosis.
