Hello and welcome to JustAnswer,
most likely something called a ventral hernia
a defect in the abdominal wall
strangely, the smaller these are the more dangerous
so it would certainly be worth getting a surgeon to look at it
the repair, if i am correct about what this is and there's not much else it could be, is pretty simple if this is done early when the hernia is small
you are most welcome
just so you know
there is an emergency condition
that can occur with any kind of hernia
and it is called an 'incarceration'
this would occur if the bulge appears but does not go away
then, over the course of an hour or two the area becomes quite painful
THIS is a surgical emergency
and while this is unlikely to happen to you, you should be aware of this possible problem.
THIS IS A GOOD REFERENCE FOR YOU
