I have been ecperiencing several symptoms.Constipation, dry mouth, extensive thirst, depression tiredness severe abdominal pain, knee pain, some chest discomfort....I went Friday for an ultrasound through the local er while I was there they told me they seen a 5cm mass. They sent me home, amd told me they would call if the cound anything else abnormal. About an hour later they called me and told me I needed to see an OB as soon as possible. I told them I had an appointment for this upcoming Wednesday....They wanted to know if that was the soonest appopnitment available Which was. They said well be sure not to miss the appointment. They would not tell me what else the ultrasound showed up. Then Friday night my stomach began to swell, My weight has gone up a little however, I look about four months pregnant. They did rule out, appendicitis, gall stones, and that type stuff. Now I am terrified that there is something really wrong. I was wondering if an Ultasound can show up cancer? I am 26, years old mother of three kids ages 4 to 6. I am mortifiied that something is really wrong...Any information that that you can give me would be greatly appreciated.
