Your finger joint might stick due to trigger finger, a common condition affecting the tendons that bend your fingers and thumb.
What is Trigger Finger?
Trigger finger, also known as trigger thumb, occurs when a tendon controlling your finger movement can't glide smoothly within its sheath. This often happens because a part of the tendon sheath becomes swollen, or a small lump (nodule) forms on the tendon. This prevents the finger from bending and straightening normally, causing it to "stick" or "lock" in a bent or straight position. It can affect any finger or thumb, and sometimes more than one digit.
Symptoms of Trigger Finger:
- A finger or thumb that catches or locks when bending or straightening.
- A clicking or snapping sensation in the affected joint.
- Pain or stiffness in the affected finger or thumb.
- A lump or nodule that can be felt near the base of the affected finger or thumb.
- Difficulty straightening the affected finger or thumb.
Causes of Trigger Finger:
The exact cause of trigger finger isn't always clear. However, several factors can increase your risk, including:
- Repetitive hand movements: This is common in jobs requiring repetitive hand actions.
- Injury to the hand or finger: Trauma can trigger the condition.
- Certain medical conditions: Conditions like rheumatoid arthritis or diabetes can increase your susceptibility.
- Pregnancy: Hormonal changes can contribute to the problem.
Treatment Options for Trigger Finger:
While trigger finger can improve on its own, treatment is often needed to improve function and relieve discomfort. Treatment options vary, but common approaches include:
- Splinting: Immobilizing the affected finger with a splint can help reduce inflammation and pain.
- Medication: Corticosteroid injections can reduce swelling in the tendon sheath.
- Surgery: In cases where conservative treatments fail, surgery might be necessary to release the constricted tendon sheath.
