The term "iPhone finger" is used to describe a visible mark or indentation on the little finger, likely caused by extensive usage of smartphones such as Apple iPhones

To determine if you have an "iPhone finger" you need to hold out both little fingers and see if the pinky finger you use to support your phone has a noticeable indent

While tech enthusiasts have expressed worries about the pinky indentation, health experts have dismissed it as a genuine medical condition

One US doctor said that indents or gaps on little fingers don't highlight a problem. "They show typical pinky anatomy, which can vary widely," the expert said, per Post

Another doctor explained while the indent on the pinky may be real, “iPhone finger” or “smartphone pinky” is not an official medical diagnosis

“You're using your pinky to stabilise and support your smartphone, and you literally indent the side of your pinky from holding your phone,” the doctor explained

Health experts, however, warned of a few other phone-related medical conditions that can arise, such as "smartphone elbow" or “texting thumb”

“Smartphone elbow” - medically known as cubital tunnel syndrome - happens to people who bend their elbow beyond 90 degrees in long durations, commonly to text

“Texting thumb” is a repetitive injury that develops from constantly holding, scrolling, and texting on a smartphone or tablet

Overuse of a phone can aggravate underlying conditions, like arthritis, or cause new problems in the thumb tendons, experts warned
