Our hands are made up of tendons, small bones, muscles and nerves that pass through one central area: the wrist. And hands and wrists are particularly susceptible to damage from the thousands of tiny micromovements we do each day — especially when actions such as typing on a phone become so repetitive. Dr. Ariel Williams, an orthopedic surgeon specializing in hand and upper extremity surgery at Yale Medicine, said she's treating an increasing number of patients who say their mobile phones have aggravated their symptoms or their issues started with some change in their mobile phone use. "It is probably a combination of the repetitive motions we engage in when we are using our phones and also being in a particular position for a prolonged period of time," Williams said. "All those things put increased stress on our bones and joints and ligaments and tendons and can also cause changes that end up causing increased pressure on our nerves." But it's not just our hands and wrists that are affected. 📸: interstid/iStockphoto/Getty Images; canart7/Getty Images, AndreyPopov/Getty Images, PeopleImages/iStockphoto/Getty Images; Ivan Pantic/ Getty Images - @cnn
