Hi, this may be better suited for a dermatologist , but my girlfriend has developed a few patches of rashes , two on her neck , and one on her eyelids. She says they are painful and itchy. These rashes have persisted for a few months now, they will occasionally improve and then worsen again. Improvement seems to correlate with prolonged time away from my apartment. We are concerned that my apartment, specifically my bed is infested with some sort of parasite. Symptoms worsen after sleeping, and it is an apartment that has been inhabited by nothing but college students for around 20 years. For all I know, the bed is equally old. She has already gone to an allergy clinic, and is planning to visit an optometrist and a dermatologist this week. Until we have this figured out, she will be staying with her parents. Is there any further advice you can offer?
