I dont think she is crazy because I have seen the welts after she claims the bug bit her. Her skin has completely changed. It does look like holes where something has dug into her skin. She pulls white threadlike pieces out of her skin and I am a witness these threads wiggle, they move on their own. She has hundreds of pieces of tape with what she gets off of her even out of her nose and she keeps it in hopes she will find a doctor to help her. Has anyone else ever seen anything like this?
This is not as uncommon as you might think. Go to google and you will find several skin conditions that mimic all of this.
Take your Mom to a dermatologist; hope she finds relief.
Any update on the bugs?
