My 8 yrs old daughter is complaining that she can t breath through her nose when she lies down. She have to stack 4 pillows and sleeps in a sitting position. Her pediatric is aware of this and she gave my daughter nose spray and oral syrup to take at night. It has been 6 months and she still complains at night. The doctor looked in her nose and saw something look like swelling. She said that when lie down it will bother her breathing. What is the problem and how to fix it? Thanks
