Ultrasound I had last week showed a 1.5 cm inguinal hernia. Is it really necessary to have the surgery? Pain in my gut isn't bad, but the pain going to the groin is difficult. Have had mesh surgery before, on same side that the 1.5 is showing up. What's weird is the catscan I just had did not show the hernia. Any help would be appreciated....can't golf, only watch!
