non-painful lump in upper left abdomen

For a few months now I have noticed that I can feel a small lump in the left side of my abdomen, about 2 inches above my belly button and below my left ribcage. It is not painful, and I can palpate it, especially after I've eaten a large meal. When I eat it seems to pop out a little bit, and to me it just feels like a baby kicking, but it's in my upper left abdomen. The only health problems I have had are a history of hashimoto's thyroiditis. I was hospitalized a few years ago with severe vomiting, diarrhea, abdominal pain and dehydration. I was diagnosed with gastroenteritis and acute pancreatitis. This is the only major GI problem I have ever had. I am very slender, 105 pounds, so I was wondering if maybe it was normal to feel a lump during digestion just because I am skinny and it's easy to feel my anatomy, or if I should be more concerned. Thanks!

LBeth, it could be an intestinal hernia. You may want to consider checking with your doctor.

Thanks CalGal, I was thinking that it could possibly be a hernia. The lump doesn't actually go through my abdominal wall, it just kind of "comes to the surface" every once in a while and I can really feel it if that makes sense. Could it still be a hernia if it doesn't actually protrude through the abdominal wall?
