It's a sign of the times--and maybe a sign of our culture. People are taking so many selfies, they're getting "Selfie Wrist." Tina Choi, 29, works in digital media promotion. She says a successful selfie can raise the profile and income of her clients. Choi believes selfies are an effective way of sharing a sense of yourself. "It’s really about telling a story. Where you're at. What you're doing. How active you are," Choi said.

But all that selfie taking started causing tingling in her fingers and wrist and later discomfort. After a few months she said it felt like a sharp pain in the corner of her wrist and it actually would prevent her from working. "It's a form of carpal tunnel because this hyperflexion of the wrist appears to cause … the nerve to become inflamed and angry," said Dr. Levi Harrison, an orthopedic surgeon. He said the problem begins when patients constantly hyper-flex their wrist inwards in a rush to capture that perfect angle.

Harrison showed her exercises to do for just minutes a day. After a few weeks, Tina's pain improved. Now she takes much safer selfies. "That is the nature of our generation right now," she said, "We're taking so many selfies these days."
