question: Hello Doctor, My daughter is 9 1/2 years old, from the age of 2 years she is been allergic to cold. She always breathes through mouth and her nostrils get blocked. When we force her to close her mouth and breath through nose she starts coughing and has continuous sneezing and running nose. We have approached many clinics, but the medicine provided was only nozil drops, cough cyrups lik biodryl, relent, quiet and sinarest. Due to which she is unable to concentrate on her studies and we are worried about her future and her health. Some doctors told that she will be fine when she is 12 years old, but some doctors told that there is nerve growth in her nose, which needs to be operated. Please advise
