Doctors treat mild cases of stenosing tenosynovitis, or trigger finger, with nonsteroidal anti-inflammatory drugs and therapeutic relief, such as hot or cold compresses, stretching exercises and splints, Mayo Clinic states. More severe cases may require steroid injections for pain or a surgical procedure to release the tension around the tendon.
Trigger finger occurs when an inflamed tendon has trouble sliding back and forth through its surrounding sheath, causing the finger to catch temporarily or lock up in a bent position, according to WebMD. People who perform repetitive motions or frequently hold tools have a high risk of developing the condition. Moderate symptoms usually heal within a few weeks by reducing inflammation with NSAIDs, allowing the finger to rest and avoiding the activities that contributed to the condition.
Doctors may instruct patients to wear splints at night to hold their fingers straight during the healing period, Mayo Clinic explains. Physicians often consider steroid injections a better option when patients are experiencing excessive pain or recurrent locking because this technique quickly relieves the inflamed tissue, restoring the tendon's smooth movement. Percutaneous release is another nonsurgical treatment, which involves using an inserted needle to loosen the tendon sheath. If surgery is necessary, physicians make a small incision in the finger and cut the sheath to give the tendon more room to move.
