Hi
I am also having the same signs/symptoms as you. The constant experience can be annoyed to me. Apart from that, I suffered from breathlessness since 2018 and that was when I came to learn that I had acid reflux after a diagnosis by lung specialist.
The constant minty / cold sensation in throat, tongue, gum and even nose really irritated me & I am feeling helpless to what is going on exactly. I visited few doctors and specialists in relation to these signs/symptoms since then. But to their antonishment for having such signs of cold sensation in throat, tongue, gum and nose. They told me they have neither come across for the same or heard of from their patients. They will only respond to me ‘I don’t know!’. And a clinic doctor repeatedly telling me ‘I don’‘t know!’ He just asked me if I am interested to see a ENT specialist. So far, I have yet visited. I have been hopeful to see if such cold feeling inside will be ceased by itself.
But no matter what medicines I tried, it seems to no result.
May I check are you still having the same symptoms as of now? I look forward to hearing from you soon.
