the dermatological magnifying microscopes are not a high enough power dr Savely says.
get a 60x mini microscope.
Also get the book by dr. ginger savely and read about the disease. Get the knowledge before you say she is delusional. And as was suggested she should get ivermectin and doxycycline. At least try ivermectin.
When it comes to parasites doctors are not trained.
