Your friend needs to get this rash checked out. It could be any number of things. It could be a fungal infection, a parasitic infection, an allergy to something, or it could even be a symptom for another disease, such as Lyme Disease.

Your friend needs to see a doctor as soon as possible, ESPECIALLY since she’s feeling pain and weakness.
