Ok, I went to the docter a few days ago. I told her the sypmtoms I had which were, Abdominal Pains, Blood In stool, and getting really tired. She prescribed me prevacid. She didn't tell me exactly what was going on. I am only 19, She said it could he hemeroidal. This was three days ago. I had a blood sample taken. and a sample from a stool. I was pretty good yesterday. i've been taking one 30 MG prevacid a day. The doc was supposed to get back to me on my test results yesterday. but did not. Today I was so out of energy I felt like I would pass out a few times. I have also been feeling more abdominal pain. Since this is only three days since I started taking prevacid, will the symptoms go away? Do you think that there may be another problem the doctor did not find? Should I be getting Better Soon? Do I need to go into the Doctor again?
