A stress fracture is a very small crack in a bone caused by repetitive stress or overuse, often seen in athletes or those who engage in high-impact activities. Unlike sudden fractures from accidents, stress fractures develop gradually over time due to repeated strain on the bone. They typically cause pain and swelling in one specific area, getting worse with activity and improving with rest. Treatment usually involves rest and avoiding activities that worsen the pain, along with possible medical treatments like using splints or casts for support.
