What you could be feeling is stool that has collected in the section of bowel that is found in this area. It is the largest part of the colon and people can frequently feel the full intestine because this is where stool is the most formed.
However, it could also be a small hernia. A hernia is where a loop of bowel finds its way through a tear in the abdominal wall. Sometimes they can have no pain involvement. Do you feel it more when you bear down as in a bowel movement? If this lump doesn't go away after a bowel movement or two, I would get it checked by the MD. If the hernia is allowed to get bigger, it can cut of circulation to the section of bowel or cause an obstruction. This can be life threatening.
