Because of OPs 3rd post. Those are standard Morgellons symptoms, and it would surprise me if someone who never heard of the condition was imagining black skin artifacts, white air floaters, etc. His Morgellons symptoms well be a result of traditional parasites. If this is the case, anthelmintics will provide the most relief.
I'm not arguing against treating it like the parasitic infection which he suspects. But to understand some of his bizarre symptoms he should be informed about Morgellons.
