Did you read my response to you, about 10 posts above this one?
First, keep in mind I'm not a doctor, have no medical credentials at all. It's my understanding that if you have an inguinal hernia you probably DO want to get it surgically repaired, but only by a doctor that has done a lot of them.
On the other hand, some argue that you can promote self-healing, as this site suggests:http://www.groin-hernia.com/herniabible/
If I were financially secure and in your position, I would at least consider going to Dr. Muschaweck in Munich, Germany. Her clinic specializes in hernias, including both inguinal hernias and sports hernias.
I'm guessing there are a few doctors around Melbourne, Australia who specialize in hernias. It's my understanding that inguinal hernias are very, very common. Best of all, when it's fixed right, you can put it behind you.
But take everything I say with a grain of salt. I may be missing something in my thinking.
