Texting Thumb Is Real, UK Hand Surgeon Warns — Here's What to Do
LEXINGTON, Ky. — What is commonly called "texting thumb" isn't just a joke or a modern complaint — it's a legitimate musculoskeletal injury that hand surgeons are seeing with increasing regularity, according to a UK HealthCare expert.
Dr. Maureen O'Shaughnessy, a hand surgeon for UK HealthCare Orthopaedic Surgery and Sports Medicine, explains that texting thumb stems from the abnormal use of the thumb caused by fine, repetitive motions in irregular postures while using a device held close to the body. The condition coincides with increasing incidence of thumb aches and pains among smartphone users.
Symptoms can range from a dull, throbbing ache to sharp, stabbing pain throughout the thumb and wrist. In some cases, nerve irritation from carpal tunnel or abnormal posture compressing nerves to the thumb and hand can lead to numbness and tingling. Other conditions may develop, including flexor tendonitis that can result in trigger thumb, or DeQuervain's tendonitis at the wrist.
Research indicates the problem is widespread. Studies show up to two-thirds of mobile device users experience musculoskeletal complaints associated with texting and gaming, with the highest prevalence in the upper neck, back, wrists and hands. Among university students, approximately 77 percent reported experiencing hand pain in one or both hands.
O'Shaughnessy recommends seeking medical evaluation if pain persists for longer than a few weeks. Conservative treatment options include wearing a brace to support joints and tendons, stretching exercises, and over-the-counter anti-inflammatory medications like topical diclofenac gel, now available without a prescription.
To prevent texting thumb, O'Shaughnessy suggests several strategies: use phone accessories like rings or collapsible tabs to incorporate other digits and palm for support; alternate thumbs or use multiple fingers for typing; take frequent breaks from screen time; consider using a larger phone or pen stylus; and try the dictation feature on your smartphone.
