Possible recurrent hernia!

I had my inguinal hernia operation 15 years ago when I was 18 with an "open" mesh procedure on my left side. I also had my right side done when i was 9. It has been wonderful up until recently. I have been very active in the last 15 years (weightlifting, snowboarding, kickboxing, etc). I was never told not to do certain exercises. Should I refrain for certain things? Recently I have been more aware of the left groin area when doing some new stretches ie. hip flexor stretches. My question is this, how likely could it be that this area was re-injured. There is no visual hernia. Nothing in the testicule area either. Just a slight semi hard bump where the lower ab meets my groin. No pain, just a little sore/tingling. Any thoughts? Would a doctor be able to do anything at this point? What type of doctor should I go to? If I do need surgery, how do I find the best Hernia surgeon in North Jersey? Thanks in advance!
