I have same thing right now, went to doc last week Told me she couldn't feel a hernia, and her diagnosis was a groin strain. She told me to take 1800 mg's of Ibuprofren a day, and call her in 2 weeks. After 1 week, pain in groin is pretty much gone, pain in lower abs is about 90% gone. She also said stay active, don't just sit around or scar tissue will form, but only go about 60%, and no explosive movements.
Best thing you could do is go see your doctor, preferably a female doc for obvious reasons.
