I've read through many of the diagnosing threads, and my head is spinning with all the different possibilities as to what is ailing me. I can't find anything that perfectly matches my situation, so I thought I'd start my own.
Spring of 2012 I was a 14:07/29:11 guy, and improved from there in the fall into the best fitness of my life. Injury in the winter of 2012/2013 skews my understanding of what may be wrong, thought I was just severely out of shape when I came back from injury in the Spring of 2013. I was minutes off my PB's in the few races I ran. Noticed these lesions on the back of my throat in February 2013 but thought nothing of them at the time -->

Also, I believe that I contracted Epstein-Barr in the summer of 2011, and that is why I have the antibodies for EBV, but not the active form. Lately I have been up and down, feeling overwhelmingly fatigued most of the time, with extremes in heart rate... usually HR is suppressed (before illness my absolute lowest resting HR was 41-44bpm in the morning - one month ago I was lying in bed at 31bpm and most recently 35bpm). After taking a few weeks completely off from running, I tried to slowly return. My HR at an absurdly easy pace (~8:00), was at about 95% of my max HR. Respiratory rate didn't match up with an effort like this, although it was elevated.
Recently I've had lower body temperature when my symptoms are worst, usually in the 95.8-96.7 range. I have also recently developed orthostatic hypotension and every time I stand up it feels like a battle not to sit right back down - lightheadedness, dizzyness, and light sensitivity.
Primary care physician is stumped, blood work mostly came back fine.
