I have the same thing I had covid in October 2022 and had sinus issues with it and then I got reflux that was in my throat and I also suffer from anxiety I am swallowing every five minutes and feel like my throat is tight I feel the popping in the left side I was told it could be inflammation and it’s making my hyoid bone do that noise since it is the only bone that floats my left ear hurts and I got tons my eustachian tube could be clogged from all the thick sinus drainage idk what’s wrong with me I can’t find the answer but anxiousness causes your throat to be tight rub your shoulders and see if that will help I feel the popping when my mouth and throat is dry more
