2 years after Hiatus hernia repair and fundoplicatipn

Had the op twice as first one failed. It's been a good couple of years and have been back at gym for a while now, most things ok. Has anyone experienced any pain doing abdominal exercises. Left of sternum slightly under ribs, not sure if it's muscle or something from the op sight, feels a bit like a server bruise or pulled muscle. Leaves me nervous as I don't want to risk pulling anything undone if that makes sense.

Exactly what I did. Interesting about follow up though. Never suggested. Only had check up a few weeks later.
