Tennis thumb, more accurately described as De Quervain's tenosynovitis, is a condition characterized by the inflammation of two tendons that cross your wrist at the base of your thumb. This inflammation can lead to pain and discomfort, particularly when moving your thumb or wrist.
Understanding De Quervain's Tenosynovitis
What Happens?
The tendons affected in De Quervain's tenosynovitis are responsible for thumb movement. When these tendons become inflamed, it can lead to:
- Pain along the thumb side of the wrist.
- Swelling near the base of the thumb.
- Difficulty gripping or pinching.
- A "catching" or "sticking" sensation when moving the thumb.
Common Misconception
It is important to note that the term "tennis thumb" is somewhat misleading. While it can be exacerbated by activities like playing tennis, it's not exclusive to athletes and can occur in individuals who perform repetitive hand or wrist movements in their daily life.
Causes
- Repetitive motions: Activities that involve frequent thumb and wrist movements.
- Overuse: Excessive strain on the tendons.
- Direct injury: Trauma to the wrist or thumb.
- Underlying conditions: Certain health issues that increase the risk of tendon inflammation.
