What are the symptoms of trigger finger?
Trigger finger is a condition that makes your fingers or thumb catch or lock when you bend them. You might notice a painful clicking or snapping sensation when you bend or straighten your finger. This is often worse in the morning or after a period of inactivity.
Other symptoms include stiffness, soreness or a bump at the base of the finger or thumb, and a popping or clicking sensation as you move your finger.
What are the causes of trigger finger?
Trigger finger is usually caused by repeated movement or forceful use of your finger or thumb, leading to inflammation of the tendon. This can also result from holding something that vibrates, such as power tools or bicycle handlebars.
The condition is more common in people with certain medical conditions like rheumatoid arthritis, gout, and diabetes.
How is trigger finger diagnosed?
Diagnosis of trigger finger is typically based on a physical examination. Your healthcare provider will check for pain, swelling, and a bump at the base of the affected finger or thumb. They may also ask you to move your fingers to see if there is any catching or locking.
How can I manage trigger finger?
Management of Trigger Finger often involves resting the affected hand and avoiding activities that cause pain. Splinting the finger to keep it straight, applying ice, and taking anti-inflammatory
medications can help reduce pain and swelling.
In some cases, corticosteroid injections may be recommended. If these treatments do not relieve symptoms, surgery may be necessary to release the affected tendon.
