The symptoms suggest that you have an abdominal aortic aneurysm, which is a potentially life- threatening condition in which the major blood vessels of your abdomen (the aorta) are weakened and begin to swell, which can cause pain and complications such as urinary reflux and sharp chest perforation.
Doctor, I've been experiencing some strange symptoms recently, having trouble urinating, a lot of back and stomach pain, sometimes sharp chest pain, what's the problem?
