she seems to have sinus problems... .and sinuses can affect the ears..... too. It Drains into each other.... and if the sinuses are inflamed, then that affects 'breathing' too. Creating blockage...
Does she have mucous from her nose or post-nasal drip???? Post-nasal drip also causes coughing... as it drips down the throat....
The sinus and ears... affect each other.
If Claritin does not work for her, then try something else. Claritin for example works for me, but does not for my Mom. So she takes Zyrtec.
The prescription "Allegra" is also good. But I don't know if they make that for kids.
I would, take her to a Specialist... and check her sinuses.
My Husband has sensitive sinuses... and always gets sinus infections. Sinus issues, are hard to get rid of... especially if it is infected....
You could also try a "neti pot" ... which is a nasal flush. Using plain warm water. My daughter, at that age, could and would use it... when she had a clogged nose from colds. My Husband uses it daily. Many Doctors recommend it. You can get it at any drugstore or Whole Foods.
Sure, it may be allergies. Probably is. BUT... it is her sinuses.. .that are inflamed/blocked and probably causing post-nasal drip, coughing and the ear infections....
That is my guess....
It is ridiculous... that the Pediatrician will not refer her to a Specialist. Even if it is for allergies... their current recommendation of Claritin is NOT working for her. AND you the parent, are requesting a referral to a Specialist... so they SHOULD do so.
Ask them again...
all the best,
Susan
