I have a lump that has just come up inside my belly button.  I am concerned about it because I also have a diaphragmatic rupture that I have not had the chance to repair because I have no insurance.  I do not want the lump inside my belly button to be something more serious.
Hello hope the answer satisfies you. You mentioned that you have a small lump near belly button now if the lump increased in size on coughing and sneezing you notice it could be a para umbilical hernia, if remains constant and soft in consistency can be a soft tissue tumor. All these likely cause of swellings seems benign provided you donors have any other systemic upset. As far as your concern of diaphragmatic rupture that hasn't been repaired and could cause it is least likely. As this can cause an iatrogenic hiatal hernia in that stomach or a portion of esophagus can slide in chest. Hope it helps you thanks
