I Was Feeling A Burning Sensation On Side Of Belly

I was feeling a burning sensation on side of belly and inside front of belly by rib cage a few weeks ago. Now I have a lump a few inches above my belly on the right side. It's inside my belly and can feel only when pushed and it is kinda firm. If you press on it I hear squishy noises. What could this be? I was thinking it maybe a hernia.
