My 2 year old, 5 year old, and 40 year husband have had very sore throats, temps of 100-102 degrees, and dark brown spots on the roof of the mouth. Fever last 2-3 days. Went to the doctor, diagnosed one child with tonsillitis , the other with just an ear infection . Husband didn t go to the doctor. Kids were prescribed Ammoxicillan, and developed a rash on hands, feet, and face (tiny red spots), diagnosed as an allergy to penicillans. Just wondering about the brown spots on the roof of the mouth and other symptoms.
