Hernia usually involves penetration of the internal organs through the protective muscle walls that enclose them. One of the most common symptoms caused by hernia is irregular swelling especially in the stomach area. In initial stages, the swelling or bulge is only appeared as a small lump that does not cause pain when it is touched. As the disorder progresses the swelling or herniated area becomes painful and continues swallowing. The lump is more obvious when you cough or sneeze and usually it can be pushed back with your hand, but it will bulge again in a short time. Be aware if you can't push back the herniation, you might be suffering from a strangulated hernia, an extreme form of hernia and requiring extreme hernia surgery.
