Smartphone Use Triggers ‘Texting Thumb’ Pain, Experts Advise Breaks and Ergonomic Tips

Extended use of smartphones can overload the thumb, wrist and hand, leading to pain at the base of the thumb, stiffness, tingling, a clicking sensation and occasional numbness. The condition, known as “texting thumb,” is not a formal diagnosis but a set of symptoms caused by repetitive motions and the increasing size and weight of modern phones.

Dr. Maureen O’Shaughnessy of the Hand Center at the University of Kentucky HealthCare explains that frequent breaks, alternating hands, using the index finger more than the thumb, voice‑typing, larger font sizes and supportive accessories can reduce strain. Simple wrist and finger stretches also help. She adds, “Portable devices are here to stay. Instead of telling people not to use them, we need to find ways to integrate them safely into modern life.” Reducing phone use, for example while on vacation, often eases the discomfort.
