Hi, I cycled for about a year on trike and bike before having the hernia diagnosed. My memory fails me, but don't recall any probs cycling. Had a keyhole repair last April, back on the bike after 4 days, but only managed a few yards! Kept at it and was up to 100km by the end of June, didn't progress any further as a heart attack and triple bypass in early July/August put paid to my quest towards the hundred mile mark. I did manage to get back on my bike ten days after being discharged post op, and did approx 25 miler with local club a few weeks later. Winter has slowed me up more than expected, but the quest begins again.
Listen to your body, and try everything at a slow pace. The hernia repair had dropped from my mind, but still get occasional twinges, no worse than those pre op.
