Anyone else feel like this

[olivia01]

my name is nicole. my daughter is five. she began having cough fits when she was two. she had chronic ear infections from birth to two years of age. in fact she was one away from the tubes. one year right before she turned two they stopped. needless to say no tubes.... however the cough began. it seemed to go on all day..... sometimes relentless, and worse at night. this has continued up until now. from two to four it seemed it would come every three months. now it comes every month for the past six months. i have done cystic fibrosis testing...negative. barium reflux testing... negative...she does have allergies..trees,grass, dust. her pulminary tests range from 116-120. no pulminary prob. however i am a seriously dedicated mom.. i want to know why this happens to her moreso has anyone experienced this. she has been on antibiotics....for long amounts of time..thinking this could be an sinus infection...prednislone....singular...zy rtec....pulmicort...albuteral....xopenex ...tussinex with codeine...robitussin dm...i mean you name it i got it and refills. only recently last two times she has gotten this....i began a new regimin. pulmicort when sick or not two times a day. when sick.....what seems like now every month..i give her xopenex..pulmicort..and robitussin..along with her zyrtec. it seems to be working ...where as nothing has in the past. when i was up until 6:00am...from 8:00pm at night administering all i could possibly give. please if anyone knows why this happens..if she can grow out of it? let me know. i am leaning towards cough variant asthma. i would greatly appreciate it.
