Mine felt like a credit card was beneath the skin sometimes, but it was the mesh. My story is similar to yours, TWICE, within 12 months.I had an inguinal hernia repaired. Then the patch failed, so I had it repaired again by a more competent surgeon. I continued to have pain in the hernia area that slowly subsided over the course of a few years. It was pretty bad for a while, but not unmanageable. I'm about 3 years out from the last repair and the pain is finally gone. It can take a while for the muscles to regrow around the mesh. Some folks feel better after a few days. I was not one of those folks.
