Hmmm, all good considerations, and I thank all of you for your caring responses.
SOme replies -- yes oh yes did I ever consider leukemia. My younger son has a very good friend who developed ALL at age 6. Her ped is also my son's ped. When he ordered a CBC and said his iron was slightly low, my heart was in my throat because all I could think of is that this is how our friend's "story" began. Evan's white count was the first thing I looked at, I admit it! And it seems ok -- no sign of that type disorder from his CBC, anyway.
I also considered diabetes. I am surprised and confess -- the doc did not do a glucose, that I know of. However, I will say that he does not exhibit unusual thirst nor an inordinance of urination, nor any of the other symtpoms classic of juvenile onset diabetes. But I guess a blood sugar wouldn't hurt, either, just to be safe.
And I considered cardiac, even. A neighbor of ours lost a beautiful 4 yr old dd to cardiomyopathy -- didn't even know she had it until she was gone. My father had congenital narrowing of the aorta into the renal arteries and had to have surgery, and my BIL's son was born with a coarctation of the aorta. ANd 95% of most heart defects actually have no genetic basis, even -- just bad luck of the draw. I have queried my ped about this, and he has checked Evan's pulses, etc. and while granted, we don't have a chest film or cath or such showing voila, perfect heart -- it doesn't seem to be the issue, either.
IN short, it appears my son is what could be termed fatigued, with no current "critical" medical issue (i.e. iron slightly low, congested sinuses, skin mildly pale, no fever, but with persistent fatigue, general malaise and minor to moderate pain). One thing is certain -- I'm getting a heck of a good set of baseline data here, if nothing else. If I'm catching something in its initial stages -- by golly, I'm staying n top of thsi and we are going to know it! ANd if, on the other hand, he's merely having a hard time rebounding from a "series of unfortunate events", we should only see improvement from here and it too will show in the numbers. I'm all about data... (that's how I earned my "geekus optima" seal of Tag Fairy approval...)
So an update and pathforward -- I called the ped and he's going to try a different med for Evan's still lingering sinus issues. We will give it a try -- it is clear he still has conjestion there, and if he's fighting infection, it could certainly make him feel "croppy" (and would perhaps skew bloodwork, if he's actively fighting a virus or infection like that.) Once we get him over the sinus hurdle -- we shall see where we stand. He will have lots of rest in March -- no basketball, no baseball until April, and a week off for Spring Break with no real plans. Spring is beginning -- normally, even a hint of warmer weather (i.e. above freezing!) sends my kids clawing at the door to get outside. I can better gauge his level of lethargy at that point. If he gets sick again, well, of course, I'll have him back at the doc in a heartbeat. And with spring on its way, an allergist may well be in order too, depending upon what I see.
BTW -- anybody else here read that today's youth -- especially girls -- are a few years ahead of us adults in terms of hormones / puberty? Lots of theories on why -- anything from environment to hormones in meats to societal stressors. Based on some of the responses to this thread, it sure seems true. I know in my son's class, the girls are all going through those changes that I didn't recall having (nor recalled my friends having) until we were well into 6th grade -- today's girls have a good 2 year lead on my generation.
Scary.
Thanks again for the many responses -- all are appreciated!
