My husband just had surgery for a hernia in his pelvic area. The surgery was quick (3 small cuts of which have healed very well) and he was pretty much back to work by the following week. There's a lady I know who also had an umbilical hernia but she's just now going to have the surgery nearly 20 years after she noticed it and it's the size of a head. Don't wait get the surgery asap. All they'll do is put a small film over it and voila! It's been a little over a month since my husband's surgery and he's working out, running stairs, lifting things and playing heavily with the boys but before the surgery he would always have discomfort within minutes of doing any of these activities. His was the size of a small lemon.
