Do you have a copy of those results? Did they include a T4 and a blood glucose value? What about a urinalysis?
Something like cancer (I don't want to scare you with the "C" word, but it should be considered) wouldn't necessarily show up in blood work. Were any other tests done, like perhaps x-rays or even better, an ultrasound?
