I am hoping someone out there has experienced similar symptoms as my little brother and can help. My brother has been chronically ill for 2 years now: symptoms consist of cycling fatigue where he is bed ridden for sometimes a few weeks, vertigo (generally mild constantly and sometimes severe), cycles of fever/chills, and from my own observation he appears pale glassy eyed. He has been tested for Addisons and the doctors insist he does not have it..although salt is low and high IgG levels (strange) from what I remember and it seems he usually has a cycle of illness following exercise. Also, it seems antibiotics help a little initially but then don't however, switching to another antibiotic helps again. We havent been able to get much help from the doctors they are thinking its chronic fatigue but to me appears adrenal with an underlying bacterial infection. Anyone?
