A new trend on TikTok has people worried about "phone pinky," a condition where extended phone use allegedly causes a bend or bump on the pinky finger. The phenomenon has gone viral, with users sharing images of their deformed pinkies, but experts say there's no official diagnosis for this issue. Some experts suggest that excessive phone use can cause joint problems, but many images shared online may not indicate a real medical problem. If you’re worried about getting phone pinky though, simple solutions could include just adjusting how you hold your phone or cutting back on screen time.
