Trigger thumb, also known as stenosing tenosynovitis, is a condition where the tendon that controls the movement of your thumb becomes inflamed and irritated. This can cause your thumb to catch or lock in a bent position, making it difficult to straighten or move.
Trigger thumb can be caused by repetitive movements or overuse of the thumb, such as gripping or grasping objects for long periods of time. It can also be caused by medical conditions such as arthritis or diabetes, which can lead to inflammation and swelling of the tendons in the hand and wrist.
The symptoms of trigger thumb include pain and stiffness in the thumb, as well as a popping or clicking sensation when you try to move it. You may also notice a bump or nodule on the palm side of your hand, near the base of your thumb.
Treatment for trigger thumb typically involves rest, ice, and anti-inflammatory medications to reduce pain and swelling. Your doctor may also recommend physical therapy exercises to help improve the range of motion in your thumb. In severe cases, surgery may be necessary to release the tendon and allow for normal movement of the thumb.
If you are experiencing pain or stiffness in your thumb, it is important to seek medical attention to determine the cause and appropriate treatment. With proper rest, medication, and therapy, most cases of trigger thumb can be successfully treated without the need for surgery.
However, if you do require surgery, it is important to follow your doctor's instructions for post-operative care to ensure proper healing and recovery.
