For that type of hernia, I believe you can only have surgery to fix it. I'm not sure if you're aware, but all a hernia is is a bulging of a piece of the intestine through a weakened part of the abdominal muscle, in this case its showing, i'm assuming in your groin and probably worse when you cough or sneeze. It sounds serious, but the biggest complication of a hernia is strangulation of a piece of intestine when it gets stuck in the hernia but that is rare, especially in adults. Most hernia surgery is elective. Plz dont go by my advice, go by ur doctors because he may have more reasons as to why he wishes you to have the hernia repaired. However, most of the time hernia repairs is an elective surgery and I haven't encounted a patient who had a serious complication from the hernia itself. The surgery itself can keep you out of any time of serious activity for 6-12 weeks post op. Hernia in that region can cause a slight chance of sexual dysfunction as well.
What is the symptoms ur experiencing? Does the lump or bulge move? Hurt? Pop out more after lifting heavy weights? Do you get a feeling of tugging or pressure in the groin? Can you push the hernia back into place when it's popped out? Reasons I'm asking is cause I want you to be completely sure that is a hernia and not something else more serious. Any lump that is kind of rubbery and can be moved around usually is benign. If possibly I would see a doctor just to make sure.
