A few simple stretches can ease thumb and wrist pain from phone use. Mobile phones have gotten bigger and heavier over the years. Experts say repetitive typing and swiping can lead to more serious issues like thumb arthritis and carpal tunnel syndrome. When scrolling, mix up posture by switching the phone between hands and tapping with different fingers. Get a grip accessory for the back of the device to distribute weight more evenly. To ease soreness, flex the wrist back and forth and move each thumb in slow circles. If symptoms get more serious and don’t go away, see a doctor.
