How Does It Feel When Your Fingers Lock Up?
The sensations involved when your fingers lock up can vary by person.
Factors such as the problem’s location, cause, severity, and duration can change how it feels.
You may feel the affected joint “pop” into place as you straighten your finger.
Without Pain
Symptoms of finger locking typically begin gradually.
These symptoms may improve throughout the day as you increase the gentle use of the affected fingers and hand.
With Pain
Trigger finger is one of the most common diagnoses of hand pain in adults.
Most people with locked fingers have pain or discomfort, especially during an activity like gripping.
The sheath acts like a tunnel to keep your tendons in place.
This can happen if part of the tendon sheath becomes inflamed or the tendon develops a small lump.
In most cases of trigger finger, the exact cause of the condition is not known.
The decision to have surgery typically depends on the degree of pain or loss of function involved.
Getting a prompt diagnosis and treatment can help you achieve the best results.
The problem can cause locking or clicking when you bend or straighten the affected finger or thumb.
It can limit function and worsen over time.
Finger locking can also occur due to other problems that affect your joints or tendons.
Having certain health problems like diabetes can also increase your risk of finger locking.
Nonsurgical treatment can often relieve symptoms.
When these treatments do not work, surgery can usually cure the problem.
Starting treatment early can improve your chances of getting relief.
Resting and avoiding movements that worsen the problem can often provide relief.
Cortisone shots and surgery are options for more severe cases.
