I have Morgellons disease and all the horrible skin symptoms as described, however previously, I did have black
specks, was DX
with IBS, Fibromyalgia, arthritis, mmigraines, mixed connective tissue disease). The common thread among Morgellons victims is white, blue, red, green fibers that can be very fine like lint that can emerge from pores after bathing, or from sores, or specks, and sand particles of white, and black, and much more.
Good luck and if you don't have please pass the word.
