I had laproscopic inguinal hernia surgery about 6 months ago, and I can still feel things moving when I laugh in my groin. Doc says it feels ok.?

Probably fine. If the hernia recurs you will have a bulge and if gut in the sac you may feel that. Surgeon would see or feel that with the exam. You may be feeling your intestine move in the abdomen in response to stimulus from laugh or cough.
