Best case scenario and worse case scenario; how dangerous is a epigastric hernia if not treated within say a month?

Missing info. Hernias come in all sizes from near undetectable to grapefruit size. They may or may not include trapped tissue or bowel that could result in severe complications if incarcerated. You are welcome to start over and describe the issue in detail. A site doc may decide there is enough information for a comment. The best answer would come from the doc who examined you.
