Trigger finger is a condition that can occur in people with diabetes, in which one or more fingers become stuck in a bent position and then suddenly snap back into a straight position. It occurs when the tendon sheath in the affected finger(s) becomes inflamed or thickened, causing the tendon to catch or get stuck as it moves through the sheath.


The exact cause of trigger finger in people with diabetes is not known, but it is believed to be related to the damage that high blood sugar levels can cause to the connective tissues in the body. Over time, this damage can lead to inflammation and thickening of the tendon sheath, which can cause the tendon to catch or get stuck.


Symptoms of trigger finger may include a clicking or popping sensation when moving the affected finger(s), stiffness or a feeling of locking in the affected finger(s), and pain or discomfort in the affected finger(s).


Treatment for trigger finger may include physical therapy, medication, or surgery. Physical therapy can help to improve flexibility and range of motion in the affected finger(s), while medication can help to manage pain and inflammation. In some cases, surgery may be necessary to release the tightened tendon sheath and improve mobility in the affected finger(s).


It is also important for people with diabetes to carefully manage their blood sugar levels to help prevent further damage to the connective tissues and reduce the risk of developing trigger finger.


If you have diabetes and are experiencing symptoms of trigger finger, it is important to see a healthcare provider for an evaluation. Early diagnosis and treatment can help to prevent complications and improve outcomes.
