Trigger finger, also known as stenosing tenosynovitis, is a condition that causes pain, swelling, and difficulty moving the fingers or thumb. It occurs when the tendons in the fingers or thumb become inflamed or swollen, which can make it difficult to straighten or bend the affected finger or thumb.
Symptoms of trigger finger may include:
- Pain: Pain may occur when moving the affected finger or thumb, especially when straightening or bending it.
- Swelling: Swelling may occur around the affected finger or thumb.
- Difficulty moving the finger or thumb: The affected finger or thumb may feel stuck or may pop or snap when moved.
- A bump or nodule: A small bump or nodule may be felt along the affected finger or thumb.
Trigger finger is often caused by repetitive hand movements or overuse, but it can also be caused by conditions such as rheumatoid arthritis or diabetes.
Treatment for trigger finger may include:
- Rest: Resting the affected finger or thumb and avoiding activities that cause pain can help to reduce inflammation and allow the tendon to heal.
- Splinting: Wearing a splint can help to keep the affected finger or thumb straight and reduce movement, which can help to reduce inflammation and allow the tendon to heal.
- Stretching and strengthening exercises: Stretching and strengthening exercises can help to improve flexibility and strength in the affected finger or thumb.
- Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs, such as ibuprofen or naproxen, can help to reduce inflammation and pain.
- Corticosteroid injections: Corticosteroid injections can help to reduce inflammation and pain.
If conservative treatments are not effective, surgery may be recommended to release the tightened tendon and allow the finger or thumb to move more freely.
It’s important to see a healthcare provider if you are experiencing symptoms of trigger finger, as early treatment can help to prevent the condition from worsening.
