Skin Paranoia

My sis-in-law has claimed to have quit but she still has a very broken out face.
She claims it is impetigo, but also claims that her children have it. All I see are freckles and mosquito bites, but she swares vehemently it is true. In the past she has also claimed that she and the children have had lice, chiggers, and boils. Is she skitzing, or am I?
i was in rehab with a woman, who would pick at imaginary spots until they became actual wounds....as for an explanation as to why her kids have it too, she may be right...impetigo is a very contagious infection, and she may be telling the truth.
