The user here named Silverfox was working with an ND in order to kill pinworms in a patient..
It is crucial to wash all bedding, undergarments, towels and such also with Miracle-Mineral-Supplement , otherwise there is reinfection and this may be why it is not going away for you...of course Miracle-Mineral-Supplement will work, and you will need to find the proper amount to add to your laundry.
Silverfox is the one to pester about this one...
He personally assisted a patient in healing their pinworms.
It can go away, and you should find out from him how exactly.
Sorry you are going through it...it sounds yucky.
