Felt tear near bellybutton. thought i had hernia. ultrasound clear. stomach feels heavy, upset stomach. bending i feel pressure. what could this be?

Could be hernia: the way you describe it most likely it is a hernia ultrasound is not the best test for hernia the best test is physical examination some time the defect still too small to be felt avoid heavy lifting apply heat pad to the area and continue to follow with your doctor

Do you still have: your appendix? Sometimes early appendicitis can manifest as pain in the belly button (periumbilical) region, and then generalize before localizing in the right lower are of the abdomen. Nausea is a common finding. Did the Ultrasound examine the Aorta and major blood vessels in the abdomen? Did you have any blood testing? Its time to call your doctor to ask what to do next. They may send you to ER
