When my daughter was 7, she had surgery for her Hernia.
There are many different types.
Her's was an Inguinal Hernia.
But Hernias are a "hole" or weakness in the abdominal wall... and thus, the internal organs or intestines can poke out of it. Hence, a Hernia can bulge out etc. In my daughter's case, it was the ovary and intestine that was protruding out.
Some say a hernia can self close. It can, but it also can not, do that. In my daughter's case, her's was causing pain and complications.
She had to have the surgery.
Carrying or lifting heavy things, can make it worse or cause more pain.
So don't do that.
Also, if a Hernia closes up... and there is an internal organ protruding out when it closes up... the internal organ can "strangulate." Meaning, the internal organ that is protruding out of the hole, can become gangrened. Or in other words, strangled. And because the internal organ becomes "strangled", it then gets circulation cut off to it and that part of the organ that is protruding out, and it can gangrene etc. In this scenario, it is very serious by that point, and Emergency surgery is needed.
An example of what "strangulated" is: imagine, your fingertip having a string wrapped tightly around it. After a bit of time, the tip of your finger will get all red, loose circulation, and you can lose that tip of your finger due to gangrene. If circulation to it, it not regained.
A hernia becoming strangulated, happened to the son of my daughter's Surgeon. And his son was FLOWN to the ER, for surgery. By that time the Surgeon said you have about 1-2 hours to perform the surgery... or you can lose that portion of the organ or get gangrene etc. and it is very serious.
You need to be referred to a Specialist. A Surgeon, who specializes in Hernia surgery. My daughter saw a Pediatric Hernia Surgeon. For example. Her surgery was laparoscopic. General anesthesia. And it took about 1 hour.
My daughter was having pain and the "bulge" was getting worse and therefore, per the Surgeon who evaluated her... she had to have the surgery. It was too risky, to not do anything about it.
There are different ways of repairing a Hernia.
So, you need to see what the solution would be for YOUR case.
All the best.
