the symptoms you are giving goes more in favour of an allergy
this however does not rule out infections causing similar rashes like chicken pox
the presentation favours more allergy than infection cause infection appears in a specific way and is usually preceded by fever
it looks like your daughter is allergic to nuts.
avoid nut. if her symptoms persist or she develops new symptoms take her to a near by hospital or consult a pediatrician
for the same.
allergies can be very dangerous so do consult a medical facility if you feel her symptoms are worsening.
i hope your daughter a speedy recovery.
