Thank you for your question,
I’m Dr. Saha and I’ll try to help you.
From your description, it is likely to be umbilical hernia.
I am sorry that you have developed this hernia.
This develops from an weakness of the muscular support there.
It can occur in obese or overweight conditions.
In small children, it can get corrected as the child grows.
However, in adults operation is the only way to correct it.
Surgery has little risk & you can go home the same day.
If left untreated, the hernia can get bigger, can be painful from obstruction or strangulation.
Obstruction or strangulation are emergency conditions.
I would suggest to have an evaluation by a surgeon.
I hope this information helps.
I will be happy to assist, if you need any clarification.
Please feel free for any follow up query.
