My daughter who is 4 complains of bad smell in her nose. Started this morning. She has a bit of a sore throat as well. She was in Avamys spray for the last three months and montair lc. This was because she had allergies and was snoring a little. We did an allergy test a few years back and it all came out negative. We took an x ray of adenoids a few months back and it was normal. She's now saying bad smell in nose. She has polyps which looks the same for the last few months. She has been running her nose a lil as well last few days. Please suggest what this can be and how to take this forward. Thank you.
