The cause of trigger finger is generally unknown. However, it is found more commonly in women than in men as well as in those suffering from other health issues, such as diabetes or rheumatoid arthritis.
Symptoms of trigger finger include a lump in the palm, pain when straightening your fingers, and swelling. Severe cases inhibit patients from extending the affected finger.
The hand and wrist doctors at Sports Medicine North say a surgical outpatient procedure known as trigger finger release can be necessary in some cases. A patient can expect to wear a bandage for a few days following the procedure as well as undergo light exercises to restore mobility.
