<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello Doctor, My daughter is 9 12 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  <response>: Hello, Thank you for asking at Chat Doctor. I went through your daughters history and understand your concern. I would like to know more about her like - Has she had any CT scan of sinuses done so far? Has her nose been ever examined by an ENT surgeon from inside? If yes, what is her status of sinuses and adenoids? Does she snore while asleep? For allergies - What are the best and worst seasons for her? Has she ever had wheezing or breathing difficulty? Does she regurgitate or have heartburn, especially after hotspicy foods? Does she have any other medical conditions? From your history, I would like to make following suggestions to you:1. Were I treating her, I would prescribe her an intranasal corticosteroid spray like mometasone or fluticasone propionate for at least 2-4 weeks depending on response.2. I would also suggest her allergy testing which will identify the substances that cause troubles to her and also to know how to avoid them.3. A detailed consultation and evaluation by an ENT surgeon is necessary to make suggestions regarding further management. If she has structural defects like deviated nasal septum, she may require surgery. If she has disorders like adenoids, chronic rhinosinusitis, appropriate medicines can be suggested, and if they fail, surgery may be advised.4. Please avoid exposure to dusts, smokes and air pollution to her as much as possible. Hope above suggestions will be helpful to you. Should you have any other query, please feel free to ask at Chat Doctor. Wish your daughter the best of the health. Thank you Regards.
