a quick update with the good news (so far): after a morning at the white plains hospital center where i underwent both a colonoscopy and endoscopy (talk about getting it from both ends - ha), my doctor found no evidence of internal bleeding!
while the cause of my anemia is still a mystery to be solved (and both of my doctors believe that my running mileage, alone, isn't the cause of such low blood work numbers), i'm now on iron supplements (slow fe 2x a day). the supplements should kick in relatively quickly - but the real issue is finding and treating the cause of the problem (not just the symptom - anemia).
still, i'll take all the good news i can get!
up next, a trip to norwalk tomorrow morning to volunteer at don's lightfoot (norwalk) half marathon. if i can't run it, can at least man a water table :D
