I have heard that Morgellon's disease is a type of fungal fiber, possibly related to aspergillus. I had a systemic aspergillosis infection, which began in my sinuses and lungs, got so bad I could hardly breathe and was deaf in one ear.
However, I took high dose iodine. I started out with 300 mg (not mcg) per day at 4 am all in one dose of Iodoral (to allow it to raise full body level of Iodine before eating or peeing) . This started to cause die off but after 6 weeks my asthma was gone and after about 3 months I was coughing out dead "polyps" from my lungs and getting them out of my sinuses. When my lungs, sinuses and ears were clear, I reduced my dosage to 200 mg (not mcg) per day for 2 more years until my blood tests for Aspergillus IgG came out normal.
One thing I noticed was that my skin became beautifully healthy and so smooth like a baby. I looked it up and 20%of the Iodine our body needs is needed for the skin to utilize vitamins effectively.
I think it is worth a try, since iodine kills all fungus, bacteria, viruses etc, and is safe in megadoses, to try this for Megallon's disease. I had my thyroid tested once a year, but no problems developed with that.
