Personally, I'd go to an internist or general surgeon who operates on hernias and have them examine me, maybe do an ultrasound. I'm sure you know that a ruptured hernia can be dangerous so it's better to know for sure.
Wondering how you are, maybe you can post. I feel badly that you didn't get any other replies but I guess nobody can know...please let us know how you're doing. Hope it is indeed just a strain of some kind.
