You may see or feel a lump, bulge or swelling under the skin. It may be a bit uncomfortable. The swelling will often disappear completely when you lie down, as the contents of the hernia sac slip back through the hole into the abdomen. It may also be aggravated by coughing, sneezing, etc.
Sometimes there is hardly any swelling to see, but you may be conscious of a strange feeling in the groin when you are standing or walking for any period of time.Many hernias cause no pain at all, but that does not mean they are not there or that they are not in need of attention.
