In reply to bouldery bits:
Your circumstances are relative only to you so I can only say what happened to me. I am a hill walker, biker, runner. Four years ago I had key hole surgery for an inguinal hernia. I did not feel pain from the hernia site. My surgery was free under the UK National Health Service. After surgery I did pay for advice from a sports therapist, these people may be a bit more understanding of how keen we are to return to our sporting ways.
The programme I followed after researching various sources.
First week rest after surgery.
Weeks 2-4 short walks (2mls) x 3 a week and some light stretching.
Weeks 4-6 slowly regain strength. Cycling and swimming useful i.e less load bearing.
It takes approx. 9 weeks for the scar hardening to go.
No serious exercise for 4 months, stop anytime if pain is felt.
Might be cautious but I guess the last thing you want is to undergo surgery to repair a surgery.
