Before I found out about my mold exposure, and I had some years of increased colds, sore throats and chronic chills. It was frustrating.
Little did I know my immune system has reached a state of severe depression after prolonged mold exposure.
Generally, when the immune system encounters a new threat, it revs up into action. This may show in a heightened WBC count. But it is not designed to deal with a prolonged threat.
