I have this and it could be the cause of my ongoing sore throat.
Googling yesterday, I found and old thread from this forum in 2015. The poster had an ENT appointment and was told that is can be caused by the menopause. Dry throat, phlegmy throat
My nose has been dry and sore on and off for the past two years, I have only just joined this up to menopause, as until a few months ago I had no other symptoms.
