I am curious how some readers determined they had CFS? Did they start feeling ill and then get viral anitbody tests? That is what I have done but, I am still not sure as it seems to be controversal. I am curious if my levels seem high to anybody reading. HHV6- was 1:80 and EBV was- VGA IgG 1:640, VGA Igm 1:10 and EB Virus Early 1:40. Do these seem abnormal? After reading some things my levels don't seem as extreme as many others. but then again i've only been feeling ill for about 3 months. I have also had low vit d and magnesium in my bloodwork and low but normal level killer cells. I have been feeling extremely exhausted with light brain fog that just doesn't clear but, is better at times. One of the most noticeable things I have experienced is awareness of my heartrate. It doesn't seem to be too high or low but, just really hard, I feel it in my back of neck/head when do some light exercise. And I notice it alot when I am sitting or laying down. I don't seem to have alot of the other symptoms of CFS like muscle pains, or troubles sleeping. But, i have randomly just felt like my mind is going to shutdown on me and I cna't do anything about it at those times it is even hard to sleep. Anyways, I was wondering if anyone has any information. It seems like everything I read out their make me more confused. Thanks for your time, Sevenpelicans.
