It is obvious you have no personal experience of parasite infestation.
Your statement proves that,because doctors do not believe the sufferers. If you had them, you would have found that already.
I have only read of one or two sufferers who have their doctors support. The rest are told they have Delusional Parasitosis.
Why are you on here?
Do you have parasites?
Or do you have a strong need to be listened to?
Go find a forum where the audience will cooperate.
Nobody here has asked you to "Save" them. Not from themselves or from Big Pharma.
You are assuming too much with regard to your quest.
