If your fingers are frequently stiff and uncomfortable, especially in the morning, you may be developing stenosing tenosynovitis, better known as trigger finger. This common condition causes discomfort when flexing or extending the affected finger, which is often the thumb or ring finger. Bending or straitening it may result in a palpable snap. In severe cases, the finger may get stuck in a bent position.
Trigger finger is the result of inflammation in the flexor tendon sheath (the protective covering that surrounds the tendons in your fingers). This causes the affected finger to become partially or fully immobilized. Prolonged inflammation may result in nodules forming in the tendon, thereby restricting the finger’s movements even further.
Typically, trigger finger caused by unusual and forceful hand activity will respond well to rest, a splint and anti-inflammatory medication. However, severe cases and those caused by a chronic health condition such as arthritis may require a corticosteroid injection to be resolved. Should this treatment fail to produce results, surgery will likely be necessary.
If you think you may be suffering from trigger finger, be sure to make an appointment with your doctor.
