Have you checked out the morgellons forum? Just a thought.
Also fatigue & itchy skin can be correlated to hypothyroid problems. Many people are hypothyroid and/or hypoadrenal & have no clue. Perhaps see the stopthethyroidmadness.com site re both issues, ditto Dr. Michael Lam's site & he has an Ask Dr. Lam forum here.
Blood tests are not always accurate for either condition, but those sites give you more info.
