Exam needed: Your symptoms warrant an evaluation and I suggest going to the hospital emergency room where prompt examination and testing are available. You experienced a lot of retching last Thursday and may have strained your rib cage. The lump has to be examined by a physician in order to make a diagnosis. An abdominal hernia or diastasis of the abdominal rectus muscles are possibilities.
