Causes
Repetitive Strain: Repetitive and prolonged use of the fingers and thumb, involving gripping, grasping, or repetitive movements, can result in irritation and swelling of the tendon sheath. This is frequently observed in individuals involved in tasks demanding manual dexterity or forceful hand use.
Systemic health issues: Diabetes, rheumatoid arthritis, osteoarthritis or gout, are strongly associated with an increased risk of Trigger Finger or Thumb. These conditions can cause systemic inflammation and changes in the connective tissue, thereby predisposing individuals to tendon-related problems.
