I have had a knotted stomach for couple of days, I feel like vomiting and its making my sense of smell heightened to the point I can't stand the smell of food.
It is probably an Umbilical Hernia. You probably have had the weakening in that area since birth and it is now bulging outward/herniated- is where the intestines push out through a small tear in the lining.
Nothing may ever be required for treatment as long as you don't start having problems, such as pain, the area getting bigger-all of them do have a tendency to get larger slowly or if signs of strangulated intestines becomes apparent. But until repaired it will always be there and has a possibility of reoccurring after that if the mesh cloth they use in repair comes loose of you lift too much weight or strain and tear it again. I Hope This Helps
