While rubbing my son's stomach a few months ago, I found a small lump (about the size of my thumb tip) midline about 1" above his bellybutton. Today, I felt a smaller (about the size of my pinkie finger tip), firm lump just below his rib cage on his right side. Considering that he had an umbilical hernia that healed on its own, I could understand he one. The second is freakng me out now. Any guidance or advice from anyone is appreciated!
