Many patients with chronic groin pain may be suffering from an undiagnosed sports hernia injury, even though they weren't injured during an athletic endeavor. Twisting and lifting such as occurs when unloading a truck or working on an assembly line is a common mechanism of injury. Even severe vomiting or slipping on ice can cause real groin injuries of this type. Not uncommonly, these patients have been told they did not have hernias or have had a hernia repair that did not relieve their pain. CT Hernia surgeons are regional experts in diagnosing and treating many types of chronic groin pain including occult sports hernias.
