I have seen this happen when a person does a
parasite cleanse and realizes they have parasites. Even with the proper cleansing and no evidence of further infection - they simply "go off the deep end" and think that even bits of dry skin are parasites. They will
parasite cleanse themselves to the point of poisoning their bodies.
I have also seen it in hypochondriacs and yes - they will pick themselves and scratch themselves in unbelieveable degrees - when in reality - there is nothing there.
The really sad thing is this - doctors know about delusional parasitosis - so when a person with Morgellon's or strongyloides comes in for testing and treatment - they are told they are "crazy" and that they have "delusional parasitosis". They can't get any help from their doctors adn most can't get much support from family and friends either.
