Just had surgery for it last year. I had the belly-button kind. Had it for ~10 years and finally had it taken care of. In and out the hospital in about 4 hours.
Had the mesh put in. Obviously everyone is different, but I had very minimal pain. Didn't even need the pain meds they gave me. Took 6 weeks off from the gym, which was the worst part (out of precaution, but was a must for me). No work for week and a half and stayed off my feet whenever possible. By the 8 week mark, I was fully back at the gym (whole routine back with squats which I held off on a little longer than everything else).
Not sure what you mean by back at it, but I'd assume your talking about getting back to your routine and not revenge on the hernia itself. lol
