As explained in the video above, trigger finger is a very common and painful problem. If you have trigger finger the tendons in your fingers are inflamed. Because these tendons are covered by a structure of tissues called a sheath, they will not glide properly if swollen. This means that your finger may lock, bend, knot, or snap. Trigger finger can occur in ANY of your fingers, including your thumb, index, middle, ring, and pinky.
The bones in your fingers are known as phalanges and you have 14 in each hand. Each of your fingers have 3 phalanges, however, your thumb only has 2. The muscles that allow for movement in our fingers are located in the forearm. We have long tendons that attach these muscles in our forearm to the bones of our fingers. These tendons are covered in a tunnel-like structure of tissues, called a sheath. When you bend your fingers the tendons slide through the sheaths to keep them in place next to your bones. If you suffer from trigger finger the sliding of the tendons through the sheath is interrupted by inflammation of the tendons.
You may have heard your doctor or a friend refer to your finger issues as stenosing tenosynovitis. To be clear, stenosing tenosynovitis and trigger finger are the exact same condition. Stenosing Tenosynovitis is the true medical term for trigger finger. The word tenosynovitis means inflammation or swelling of the sheath surrounding the tendon. This is most common in the wrist and hand areas. The word 'stenosing' implies the abnormal narrowing in a blood vessel or some kind of organ structure.
There is no clear and definitive cause of trigger finger. However, there are some clear circumstances that make trigger finger more common or at least increase your chances of getting trigger finger. These include the following:
Often times different medical conditions are seen all together on the same patient. When it comes to trigger finger, it often is seen alongside Dupuytren's contracture and carpal tunnel syndrome. Dupuytren Contracture is caused by the thickening of tissues in your palm, causing your fingers to unnaturally flex. Carpal tunnel is generally numbness, tingling, or weakness in your hand because of pressure on the median nerve in your wrist. All of these conditions are even more common in those with diabetes.
Research has shown an increased chance of the development of trigger finger in people who have diabetes. In general, people with diabetes tend to have joint issues that are usually related to the stiffening or thickening of connective tissues. Some people believe the high glucose levels of a diabetic may stiffen the collagen in their bodies. Obese individuals are more likely to develop diabetes, therefore, making them more susceptible to issues with trigger finger.
Rheumatoid arthritis is a chronic disease that causes inflammation in the joints. This can occur throughout your body including your fingers, wrists, ankles, and feet. There is a clear connection between rheumatoid arthritis and trigger finger as your chances increase greatly if you are susceptible to inflammation.

It’s also important to note that there is roughly a 4:1 ratio of women to men who have trigger finger. It becomes the most common in women ages 40 to 60 years old, although the reason for this is unknown. We will likely begin to see more and more cases of trigger thumb because of the increasing use of our fingers for technological devices, like texting on our mobile phones.

Often times your doctors will check your palm for any type of lumps that may present, as this is a symptom of trigger finger.
Trigger finger is most commonly seen in your thumb (often called trigger thumb), your middle finger, and your ring finger. However, it happens in any and all of your finger. It’s possible that you are experiencing trigger finger in more than one of your fingers at a time.
