this could be a small epigastric or paraumbilical hernia
. This is not serious. It occurs when a gap develops in the muscle layer and a small area of tissue, usually fat, protrudes through. This is often intermittent and may only occur when the pressure in your abdomen is raised. When you push on the area, you may be pushing the tissue back through the gap in the muscle and therefore relieving the pain.
It is a condition that can occur after childbirth as the muscles get stretched and weakened during pregnancy
The treatment is usually a small operation to repair the gap in the muscle and this cures the problem.
