Trigger finger, medically known as stenosing tenosynovitis, is a condition affecting the tendons in the fingers or thumb. Here's an overview:

Causes

  1. Repetitive Movements: Frequent and prolonged use of the hand, especially during gripping actions.

  2. Medical Conditions: Conditions like rheumatoid arthritis, diabetes, and gout can increase the risk.

  3. Age and Gender: More common in people aged 40 to 60 and tends to occur more in women.

  4. Forceful Hand Use: Activities requiring forceful hand use or gripping.

  5. Genetic Factors: Some people may have a genetic predisposition to develop trigger finger.

Symptoms

  1. Finger Stiffness: Particularly in the morning.

  2. Popping or Clicking Sensation: When moving the finger.

  3. Tenderness: At the base of the affected finger or thumb.

  4. Finger Locking: In a bent position, which suddenly pops straight.

  5. Nodule: A small bump or nodule in the palm, at the base of the affected finger.

Treatment

  1. Rest: Avoiding activities that cause pain and stiffness.

  2. Splints: Wearing a splint to keep the affected finger extended.

  3. Exercises: Gentle stretching exercises to maintain mobility.

  4. Medications: NSAIDs to reduce pain and inflammation.
