Hello there.
I can understand your concern.
You should have attached a picture for us to getter idea.
As you have said that its swollen and protrudes beyond abdomen, then it could be a hernia also.
I would suggest you consult a general surgeon in person and get it checked out.
Do not delay it. It could be umblical hernia.
Best regards.
