We did originally think that perhaps it was a mold as the sink was pretty gross. However, after many appointments and running around the symptoms seemed to be pointing more toward TBI. But the brain scans showed no signs of trauma. This led doctors to believe it may be blood related, but any tests we did there came back normal. I am convinced that it is something blood related but it may be on a smaller scale than what normal tests can find. If worse comes to worse, I may just see if I can get a blood transfusion. I have also done an allergy panel and nothing too crazy came up that we didn't already know about. No parasites, no fungi, and no physical abnormalities were found (ie cancer, tumors, etc) I am convinced that it may be some sort of anemia.
