See answer: For persistent or severe pain seek medical attention. If the pain increases when using abdominal muscles for a partial sit up, and if it is more tender pressing in the area with the abdominal muscles tensed than with the muscles relaxed, it suggests a muscle strain of the abdominal muscles. If more tender with muscles relaxed it suggests a problem inside your abdomen that needs attention.
