Does your hand ache after a long session of scrolling through your phone? You might be dealing with what’s commonly called “texting thumb” — a broad term covering a range of discomforts tied to heavy smartphone use.
The condition can show up as general stiffness, a throbbing sensation near the knuckle, or a clicking feeling when bending the thumb. When ignored, the repeated motion of typing and swiping can develop into more serious medical issues, including carpal tunnel syndrome and arthritis.
Smartphone overuse injuries aren’t new — people have been warned about them for decades, going back to the days of “BlackBerry thumb.” But today’s phones are bigger and heavier than ever, and we use them for far more than calls and texts. Doomscrolling for hours, paying bills, and watching full movies have all become everyday habits.
“Mobile devices are here to stay. So rather than saying ‘you can’t be on your device,’ we really just need to learn and think about ways to make the devices compatible with modern life,” said Dr. Maureen O’Shaughnessy with the University of Kentucky HealthCare Hand Center.
Keeping your wrists and elbows locked in the same position for extended periods can cause soreness at the base of the thumb or wrist. Holding a phone upright for too long can also wear out your other fingers.
Dr. O’Shaughnessy noted that many people only notice the discomfort when they step away from their phones — like during a vacation — and the aches begin to fade.
The most straightforward fix is to simply put the phone down more often and take short breaks between scrolling sessions. If cutting back feels like a challenge, try switching up your posture, alternating hands while typing, or using your index finger instead of your thumb.
Your phone’s built-in accessibility settings can also help reduce strain. Voice-to-text lets you send messages without typing at all, and increasing the font size means you won’t need to hold the phone as close to your face.
There are also ring and circle-shaped grip accessories that attach to the back of your phone, helping spread the weight more evenly across your hand. Many of these accessories double as stands, making it easier to prop up your phone while watching videos.
After a long day of screen time, stretching your hands can provide real relief. Try flexing your wrist by tilting your palm toward and away from you while using your other hand to gently push and pull. Dr. O’Shaughnessy also suggested bending each finger individually and making small circles with your thumbs.
For pain specifically at the base of the thumb, place your hand flat on a surface and stretch the thumb away from your fingers, holding the position for about 30 seconds.
If numbness, tingling, or persistent aching doesn’t improve after cutting back on screen time and trying remedies like ibuprofen or ice, it’s worth seeing a doctor. Ongoing phone use can worsen thumb arthritis, trigger De Quervain’s tenosynovitis — which causes sharp pain and swelling at the thumb’s base — or lead to carpal tunnel from a pinched nerve. Trigger thumb, a painful catching sensation when bending the thumb, can also result from an inflamed tendon.
Breaking the cycle of endless scrolling isn’t easy, but even small, intentional pauses to shift your posture can make a meaningful difference.
“Our hands were not designed to use phones all day long,” said Dr. Eugene Tsai, a surgeon at Cedars-Sinai Orthopaedics and Sports Medicine. “In order for us to use the phones, we have to be kind to our hands.”
