<s>[INST] im having chronic pain around my belly button aera and very weak there to and i feel like its moving around. i missed a period last month but this month its back to normal. friday g.p arranged an ultra sound after pressing near the pain. What could it be and what can an ultra sound reveal?? Many thanks [/INST] Hello there You need to get that ultrasound asap.The first thing to rule out is apeendicitis.Other possibilities are ovarian cyst.An examination would be most helpful to narrow that down. </s>
