Trigger finger, also known as stenosing tenosynovitis, is a condition that affects the tendons in the fingers or thumbs. It is characterized by inflammation of the tendons, which can cause the affected finger or thumb to get stuck in a bent position or "trigger" as it straightens out.



There are several possible causes of trigger finger. One common cause is repetitive hand activities that involve gripping or squeezing, such as typing, playing a musical instrument, or using hand tools. Another possible cause is certain medical conditions, such as diabetes or rheumatoid arthritis, which can lead to inflammation of the tendons.



Symptoms of trigger finger may include pain, stiffness, and a clicking or popping sensation when the finger is moved. In severe cases, the finger may be completely stuck in a bent position and unable to straighten out.



Treatment options for trigger finger depend on the severity of the condition and may include rest, splinting, and physical therapy. In some cases, surgery may be necessary to release the affected tendons and allow the finger to move freely again.



If you think you may have trigger finger, it is important to speak with a healthcare professional for proper diagnosis and treatment. Early treatment can help prevent the condition from worsening and may help avoid the need for surgery.

In summary, trigger finger is a common condition that can cause pain and difficulty with finger movement. It is usually caused by inflammation of the tendons in the finger or thumb and may be treated with rest, splinting, and physical therapy. If you are experiencing symptoms of trigger finger, be sure to speak with a healthcare professional for proper diagnosis and treatment.
