Hand Conditions: What Causes Trigger Finger?

Typically, people 45 and older and those with diabetes or rheumatoid arthritis may be predisposed to trigger finger. It’s rare in children. Usually, the tendon sheath becomes irritated due to overwork or injury, so people who do repetitive movements, heavy squeezing or lifting in their work can be prone to the condition. It can happen at any time and is more common than people realize.

How is it treated?

Mayo Clinic – If you’re experiencing mild symptoms, such as a small, tender lump at the base of a finger or your thumb on the palm side of your hand but can straighten or bend your finger without it locking, take an over-the-counter anti-inflammatory medication, such as ibuprofen, every day for two weeks. If your finger or thumb is locked, you may be able to use gentle pressure to force it straight or bent.

If your finger or thumb is locked, you’re not able to force it straight or bent, and you’re feeling catching or popping, the next level of treatment is a steroid injection to calm the irritation and swelling. Performed in the clinic, the injection is done in the palm of your hand. A cold spray is used to numb the area.
