What Is Trigger Finger?
The tendons are cords of elastic collagen tissue that connect your muscles to your bones. The flexor tendons run from the muscles in your wrist and along your palm to your fingers. As they do, they pass through a tunnel of protective tissues called the tendon sheath. Trigger finger, or stenosing tenosynovitis, occurs when the tendon sheath is inflamed. As a result, it will narrow, limiting the movement of your tendon. Over time, continual irritation may cause nodules to form, further affecting finger motions.
Dr. Vagner will inject these medications directly into the tendon sheath, and they will quickly reduce inflammation.
Trigger finger often develops because of repetitive hand motions. Therefore, if you tend to make the same movements repeatedly because of your job or a hobby, you are at a higher risk for trigger finger. Additionally, the condition is more likely to develop if you are a woman. Certain medical conditions, such as diabetes or rheumatoid arthritis, can further increase your risks.
Symptoms of Trigger Finger
Most commonly, trigger finger will cause your finger to be temporarily caught in a bent position. Typically, this will affect only one finger (especially the middle finger, ring finger, or thumb). Nevertheless, the condition could affect two or more digits. You may notice some pain or a popping sensation when you are able to straighten your finger. This will occur when the tendon finally breaks through the swollen area of the tendon sheath. However, in very severe cases, you may not be able to straighten your finger at all. Your symptoms will usually be more pronounced in the mornings or after long periods of inactivity.
