Mimioto, Going to the Covid Recovery Clinic in July as I was diagnosed with long covid due to GERD worsening, inflammation worsening (I am now being treated for Lupus) and this sticky mucosy saliva in the back of my throat and in my mouth....worse in the mornings. I have tried everything. I have had this thick mucosy saliva since last last October. I have been to 5 doctors and none of them know what it is. My dermatologist cultured it and it came back no thrush, just normal mouth bacteria. It isn't painful, its just annoying and I get choked on this stuff at night. I have tried everything natural, mouthwashes, prescription, etc., The only thing that has helped some is Colgate Peroxyl (It has hydrogen peroxide in it - don't swallow) rinse and spit it out. The peroxide it in helps dilute the saliva. Listerine helps for a while and so does Cepacol mouthwash. All of these last a little while and then builds back up again. Stay tuned friend.....
