I came down with CFS last Summer after a virus that landed me in the hospital with a WBC of 1.7. Ever since, I have run low-grade temperatures around 99.0 - 99.8. My temp doesn't go up til about 5:00 in the afternoon and stays up til about 8:00. I just wondered if other CFS sufferers also had this. I have had test after test after test -- Dr. says CFS is the only thing it could be as he has ruled out everything else. Just wanted to hear from other people with CFS concerning this symptom.
