Re: child with cronic cough only at home
Even though she isn't allergic, she could have an intolerance, meaning she has an abnormal sensitivity to a food, drug, even to just dust or pollen. Usually all symptoms go away once whatever was bothering her is taken away, which would explain why she is perfectly healthy once she leaves your house.
It isn't an allergy, but some symptoms are similar. coughing, swelling, and occasionally a fever or vomiting can occur. If you want to figure out what's triggering her reactions you should expose her to diffrent materials, objects, rooms, or food throughout the day then romove each one individually. If her symptoms stop after a certain object is removed, then that was the problem.
You should also clean your house as best as you can, seeing how mold, dust, pollen, and other particles in the air, carpets, and furniture can also be a problem. You might have to remove any carpets in the house if it continues.
An intolerance is normal so don't become too worried, many people have them. My brother is intolerant to chocolate, but not allergic, his test coming back normal. But he still can't eat it because he throws up and gets horrible stomach aches.
I hope this helps. ^.^
