Pediatric allergies.......thats what most of them are. With every season comes a different brew of allergens floating in the air...and many children are sensitive to those allergens.
I wouldn't put a child on antibiotics for an unexplained cough, though. My theory is if the doctor can't get to the bottom of what's causing the cough, he needs to dig harder, not give antibiotics.......as your case proved....they may work for a time, but the cough returns.
I think your idea of taking your child to a pediatric allergist is a wonderful idea! There could be something your child is having a "rhinitis" to. :kiss
In the summer months...we go from an air conditioned environment out into a hot environment into an air conditioned vehicle out into the heat again...and the cycle continues. THIS is NOT good for any of us.....especially children.
In the Winter months, we go from a warm heated home out into the cold weather and back into a warm heated environment......and so forth. This will also cause health problems.
Solution: Move to Sunny California where the weather seldom changes. :chuckle
Okay....we can't all move to my favorite place to live, so let's see what else I would recommend here:
As long as your child is in an evironment with other children, they will have whatever those other children have......colds, runny noses, coughs, itchy throats and runny noses that make them cough, and so forth...not to mention the exposure to other children's fevers and childhood diseases.
Are their molds in your home that you haven't gotten rid of yet?
Is your child's room really dusty?
Is your home really dusty?
Do you have a lot of dusty rugs on the floor? Unclean carpet?
Dust-laden drapes and curtains?
Washed the child's bed linen...including bedspread/comfortor lately?
Changed or cleaned the child's bed pillow lately? Mites abound there!
Your child may have allergens to grass, mold, weeds, certain trees, wool, a food preservative........get him/her checked for allergies.
