My daughter is 3 years old. The last couple of days after going outside to play, she came back with some type of an allergic reaction on her face. We currently reside out of the country (Peru, South America) and weather is changing from summer to a fall type weather. Last night as I was laying with her for bed time I noticed a ball type thing in her nose . Upon looking at it with a flashlight, it appears as though it is her skin inside her nostrils that has swollen. Is this a normal reaction to an allergic reaction? She has no other allery syptoms, no runny nose, no congestion. Is this something to be concerned about?
