THURSDAY, April 23, 2015 (HealthDay News) -- As the most flexible joint in your body, your shoulder can move and position your arm in many ways. But this flexibility also makes it prone to instability and injury.
Shoulder muscles, ligaments and tendons can be injured by sports, household chores and heavy lifting. These injuries sometimes take months to heal and can interfere with everyday tasks, the American Academy of Orthopaedic Surgeons says.
In 2010, about 16 million Americans visited their doctor for a shoulder problem, and more than 2.7 million were diagnosed with sprains and strains of the shoulder and upper arm, according to the academy.
