Most patients will report non-specific severe pain in the abdomen. This is usually present around the 3rd or 4th day of the illness. The abdominal pain can be misdiagnosed for almost any other illness. However, the cause of the pain is very unique.

The rectus sheath can become either torn or individual artery and or their branches tear.
