Trigger finger is a condition that can cause discomfort at the base of the finger or thumb, right where the finger joins the palm. Officially known as stenosing tenosynovitis, trigger finger can also be referred to as “trigger thumb.” This condition involves the tendons that bend the fingers. These tendons normally glide easily with the help of pulleys, which hold the tendons close to the bone. In individuals with trigger finger, the pulley becomes too thick, making it difficult for the tendon to glide.
Here are five signs that you may have trigger finger:
- Pain/discomfort at the base of the finger or thumb
- Popping-sound when you move your finger
- Catching feeling
- Limited finger movement
- Lump at the base of the finger or thumb
