The pain is often only present with activity such as gripping. When at rest, it may not hurt. Over time, if there is increased fluid production in the tendon sheath, this may cause pressure and pain even without hand use.
Swelling : Over time there may be the development of a lump at the A1 pulley. This can be due to a nodular swelling within the tendon or the development of a fluid filled cyst.
The cyst is called a flexor sheath ganglion. Stiffness or loss of motion : A trigger finger may result in loss of the ability to bend the finger.
This can be estimated by how far the tip of the finger is from the palm of the hand when the patient is asked to bend the finger as much as they can.
This is most common in chronic, untreated trigger fingers. It can be painful to try and bend the finger due to the compression of the fluid. Over time, the person may start to avoid a bent position of the finger to limit pain.
Trigger fingers can also result in loss of the ability to straighten the finger. Some patients will feel pain trying to fully straighten. When the joint does not fully straighten for several weeks, a ligament called the volar plate becomes shortened and limits motion. Mechanical symptoms : A trigger finger can cause abnormal sensations or movement that are often described as popping, catching, or locking. Sometimes these abnormal sensations occur while bending or straightening the finger, or both.
Early on, the symptoms may be mildly painful, but as the tendon and pulley interaction becomes tighter, the pain can increase. Common treatment options include, but are not limited to: Splinting at night. When someone lays flat at night, the effect of gravity on the legs is more similar to the arms, so fluid may shift from the legs to the arms.
This may increase swelling in the fingers where pain and locking can be more frequent at night and the early morning. By using a night splint to keep the finger straight, it can prevent painful locking during sleep.
However, keeping the finger straight all night could result in the need to spend some time and effort getting it to move smoothly the next morning. Many times, oral or topical anti-inflammatory medication like ibuprofen or naproxen can be tried to relieve pain and improve ability to move the finger through a large arc. Changing your activity. It may be possible to limit or space out the amount of time spent in forceful, repetitive, or sustained gripping.
Steroid injection. Corticosteroid injections, also known as a cortisone shot , can be given at any stage of symptoms or duration. However, there may be better success when they are given early. Hand therapy. Patients may benefit from some supervised and home exercises. This procedure is usually done in the doctor's office or in an office procedure room.

If you have any stiffness, catching, numbness or pain in a finger joint, or if you can't straighten or bend a finger, make an appointment with your doctor.
Trigger finger generally results from inflammation within a tendon sheath, restricting tendon motion. A bump nodule in the tendon also may form. Tendons are fibrous cords that attach muscle to bone. Each tendon is surrounded by a protective sheath. Trigger finger occurs when the affected finger's tendon sheath becomes irritated and inflamed. This interferes with the normal gliding motion of the tendon through the sheath. Prolonged irritation of the tendon sheath can produce scarring, thickening and the formation of bumps nodules in the tendon that impede the tendon's motion even more.
