Thumb Pain
Table of content
Thumb pain is a common complaint that can affect hand function and daily activities. The thumb plays a central role in grip strength, and problems in this area can therefore have a significant impact on quality of life. The pain can be due to various causes, from overuse to degenerative changes in the joint.
Symptoms of thumb pain
Common symptoms include:
- Pain when moving or putting weight on the thumb
- Swelling or tenderness at the base of the thumb
- Stiffness or reduced mobility in the thumb
- Difficulty gripping or holding objects
- Feeling of instability or weakness in the thumb
Causes
Thumb pain can have several causes. A common cause is basal thumb arthritis, a form of osteoarthritis that affects the joint at the base of the thumb, leading to pain and stiffness. Another cause can be De Quervain's tenosynovitis, a tendon sheath inflammation that causes pain on the thumb side of the wrist. Ligament injuries, often caused by trauma, can also lead to pain and instability. In addition, overuse of the thumb, for example from frequent smartphone use, can lead to overuse injuries sometimes referred to as "smartphone thumb".
Diagnosis
Diagnosis is usually made through a clinical examination where the doctor assesses symptoms and thumb mobility. In some cases, imaging, such as X-rays or ultrasound, may be used to confirm the diagnosis and rule out other conditions. An accurate diagnosis is important for choosing the right treatment method.
Treatment
Treatment depends on the underlying cause of the pain. For basal thumb arthritis, splinting with a thumb support, pain relievers, and physiotherapy can be effective. For De Quervain's tenosynovitis, rest, anti-inflammatory drugs, and sometimes cortisone injections are often recommended. Ligament injuries may require immobilization with an orthosis and, in some cases, surgery. For overuse injuries, it is important to identify and reduce the aggravating activities and to use support to relieve the thumb.
Prevention
To prevent it, it is important to avoid overuse by varying working positions and taking regular breaks during repetitive activities. The use of ergonomic aids and correct technique during physical activity can reduce the risk of injury. Strength and mobility training for the hand and thumb can also help prevent problems.
