hi i had gone through your query and understand your concerns. i would come up with two most possibilities to fit your daughter condition .these include
1.first possibility is,HYPOTHYROIDISM;blood test
for thyroid profile may confirm the diagnosis.
2.second possibility is,ALLERGY
may be the cause
The body’s defense mechanism, the immune system, reacts to the allergen as if it were a dangerous organism, in trying to neutralize the antigen, the body releases histamine
, which produces the allergy symptoms.
I hope this is helpful for you, thank you
