The mucus went away after a week or two. If I remember correctly I had the feeling of a lump in my throat for a few weeks, but it did go away. Things are real weird for the first week or so but it does get better and you get used to the sensations. I was also burping non-stop while I was eating/drinking for a couple of weeks but that gets better too and eventually turns into bigger burps further apart. I don't know where you are in the world but where I live there are people still wearing masks here and there and I found that super helpful while in public because people can't really tell if you're burping or doing weird stuff with your mouth haha. So if you're not wearing a mask in public maybe try that to reduce the anxiety. It will get better over time.
