I had the same thing for few weeks and I am a strong minded person I don't give in z after trying few sore throat meds because it started after I had a cough and sneezing after winter and it gave me a sore throat and the clicking sound came under my neck left side of my throat . After two weeks I decided to exercise my neck and I did the kind of exercise Mike Tyson does you can check it on YouTube it looks hard and scary but it's actually nothing anyone can do it as long as you don't have a neck issue and right after doing 2 sets the poping sound just disappeared immediately, I looked for it all ways bent my neck swallow my saliva and water it's just gone. There goes your remedy too bad ain't getting paid for this but I will take donations 🙏
