Are you in Oxfordshire? I had an inguinal hernia done a few months back and my surgeon mentioned they no longer treat hernias in Oxfordshire, they just leave you to it, apparently all the horror stories they were warned about just haven’t materialised.
I had an umbilical one fixed about fifteen years ago, I was back at work in a couple of weeks with no follow up problems but all hernias are different, depends on size, location, mesh, not mesh etc, etc, my inguinal one has kept me off the bike for three months as it was massive apparently and I’m still not ready to ride up hills.
