I had a right inguinal hernia, and had to have surgery. The doctors claimed that it was necessary, because the intestines could break through the muscle and possibly be strangled. A 911 situation.
I had to get a hernia support to hold it in or keep it from sagging even more. I found it somewhere on the Internet. Sorry, I don't remember where, but they are common.
As far as I know there is no natural remedy. Mine ocurred because I was stupid. I was lifting something heavy when I was already tired and sweaty.
