Trigger Finger is a good name because as you flex your finger slowly it suddenly jumps like a trigger being pressed. Trigger fingers are often stuck down in the morning upon waking and can be very painful to straighten out.
Trigger fingers are caused by a swollen portion of your flexor tendon “triggering” through the palmer band that guides them. The discomfort is usually in your finger and not your palm.
Anti-inflammatories like ibuprofen and reducing use of your finger are good initial treatments. Cortisone injections can cure. Surgery can release triggering using a quarter-inch incision. The patient returns to light duty one or two days after surgery.
