I had a double hernia operation when I was an infant (probably one or two years old). I'm a 51 yr. old male, so I don't remember, but I still have the scar. Ancient Egyptian physicians mention hernias, but the treatment mentioned was just temporary (a STRANGULATED hernia is very dangerous because it cuts off blood supply and causes gangrene because the intestine is squeezed). Check the website (scroll half way down just before "DISEASES OF THE EYE", this is an excerpt of the site:
An inguinal hernia was described as a tumor above the genitalia, which appears on coughing, and could be restored by heat application.
“If thou examinst a swelling of the covering of his belly’s horns above his pudenda (sex organs) then thou shalt place thy finger on it and examine his belly and knock on the fingers (percuss) if thou examinst his that has come out and has arisen by his cough. Then thou shalt say concerning it: it is a swelling of the covering of his belly. It is a disease which I will treat”.
That impulse on cough is the first manifestation of a hernia in modern surgical teachings. Heat application is one of the methods to reduce a strangulated hernia. The mummy of Meren-Ptah (19th dynasty) shows a sign of an open wound resulting from surgical interference.
Now check this site and scroll a little less than half way down to hernias. Especially interesting is what is written about hiatal hernias and the treatment involving TOUCH (the heat of friction/massage).
