Never heard of a "near" hernia.
Sounds like he's not quite "near" a diagnosis, may be worth having a chat with your GP.
Loads of different types of hernia, from the
cough cough it sounds like the groin is the problem area. I always think of my old knackered bike, with bulging inner tubes bubbling through rips in the tyre side walls.
The procedures for repair are quite straightforward nowadays, and the outcomes are generally good. But don't have a "near" operation.
