question: Hello, I went to the doctor after some abdominal pain I had. The first day it was for 12 hrs aprox. And the second time was for a few hours only. After that, I haven't had anymore pain. However, when doctor did my examination I could feel some pain in the abdomen, near to the umbilical cord. Now, the  doctor said I need a CAT scan and/or a colonoscopy to determine if the pain is related to the colon. It is ok to perform mentioned exams even that I haven't feel pain anymore! What is your recommendation?
