Trigger fingeralso known as stenosing tenosynovitisis a painful condition where fingers get stuck in a bent, trigger-ready. These growths, known as bone spurs, can create uneven surfaces and connection issues. This can happen as a result of small, pointed bone growths around the arthritic joints. Finger arthritis can cause popping and snapping. That was just it in the beginning, an emoji, and then it became a meme you’ll see popping up all over the digital world in your chatbox, in someone’s tweet, in a vlog by your favorite YouTuber. Arthritic joints in the fingers often cause swollen knuckles. ‘Two Fingers Touching’ refers to an emoji characterized by two index fingers pointing toward each other.

Trigger finger (stenosing flexor tenosynovitis). If the sides of your finger are red and swollen, it could be a ligament sprain of one of the collateral (side) ligaments. Trigger finger may be a complication associated with surgery for carpal tunnel syndrome surgery, especially during the first six months after surgery. People who have diabetes or rheumatoid arthritis are at higher risk of developing trigger finger. Occupations and hobbies that involve repetitive hand use and prolonged gripping may increase your risk of trigger finger. Risk factorsįactors that put you at risk of developing trigger finger include: 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. This interferes with the normal gliding motion of the tendon through the sheath. Trigger finger occurs when the affected finger's tendon sheath becomes irritated and inflamed. Each tendon is surrounded by a protective sheath. Tendons are fibrous cords that attach muscle to bone. A bump (nodule) in the tendon also may form. Trigger finger generally results from inflammation within a tendon sheath, restricting tendon motion.
