Hi there, I have a house dust allergy since almost 4 years and I am using only a spray called Beconase , and since 6-7 months I am facing problems with my voice because I am a singer so I wanted to know if this allergy may cause problems in voice when singing because I never had such problem before, simply my voice becomes scratchy and I cannot control it anymore like I use to do before and I am assuming it might be from long time allergy I had. I did the tests but 2-3 years ago and it did not resulted that high but I wanted to know is this coming from allergy because I also did some throat tests and it all resulted OK some months ago. Can you tell me if this allergy can affect the voice after a while , Thank you.
