Hi, stuffy nose, whistling sound during breathing, running nose, sneezing
,watering from eyes without fever
is symptoms of allergic bronchitis
, so need not to worry. When such type of symptoms appear don't be panic. Sudden change in the temp. and some allergens are responsible for these type of things, so visit a children specialist and he will advise you some mild category bronchodilator
and as soon as your's child become alright stop the tt. You will require this tt till your's child attain 13-14 yrs age. Need not to worry at all because this is not a serious disease, rather it is a common disease.
