The tenosynovium becomes inflamed from repetitive strain injury or overuse or due to inflammatory conditions, such as rheumatoid arthritis, the space within the tendon sheath can become narrow and constricting. The tendon can't glide through the sheath easily, at times catching the finger in a bent position before popping straight. With each catch, the tendon itself becomes irritated and inflamed, worsening the problem. With prolonged inflammation, scarring and thickening (fibrosis) can occur and bumps (nodules) can form.
At first, your affected finger may seem stiff and may click when you move it. You may notice a bump (nodule) or tenderness at the base of the affected finger in your palm. This is the spot where the tendon is likely catching.
As trigger finger worsens, your finger may catch at times in a bent position and then suddenly pop straight. Eventually, the finger may not fully straighten.
Treatment of mild cases:
Soaking in water.
For more serious symptoms:
Nonsteroidal anti-inflammatory drugs (NSAIDs).
Steroids. An injection of a steroid medication
Percutaneous trigger finger release.
Surgery release of the tendon.
