I was diagnosed with a small umbilical hernia this past summer.... I have a sliding hiatal hernia,have several small tumors in my liver and kidney. No one seems concerned. over the past couple of months my pain has become chronic, chandged to general stomach pain not so much around the navel .....saw a gynecologist, endocrinologist, gastroenterologist, primary doctor. Has ultrasound,endoscopyx2, colonoscopy, blood work nothing but the small tumors and hernia showed up. When I sleep on my side , I feel nauseous and uncomfortable as well as in a sitting position. I no longer have health insurance so, I hesitate to call any of my doctors for further evaluation. I am 63 y/o female.
