I would like to refer you to several professionally written papers by Joseph Keleher on Morgellons.
Joe has written many outstanding articles on Morgellons, including the most exhaustive paper on the historical perspective of Morgellons dating back to near ancient times.
Joe has a category of his own on this blog that you can click at any time and see all of his articles.
HOWEVER, the articles referenced in the link below I do not believe have been published on my blog and I think you will benefit greatly by reading them. Please click the link below to access the articles.
