The human hand is a very complex part of the body. While the task of flexing a finger might seem quite simple, there are numerous tendons at work helping us accomplish our daily tasks. Trigger finger occurs when an irritated tendon thickens, making it difficult to glide through the pulleys that surround it. As the tendon becomes more irritated, the tunnel in which passes also becomes irritated. All of this causes decreased motion in the affected finger, causing it to catch in a bent position and pop or snap when it’s opened. Depending on the severity of the symptoms, steriod injection can be the solution for trigger finger. Injections are done in the clinic, and surgery is done as an outpatient.
