Hi! For the past few days, it feels like there is something stuck in my throat. It's not very painful, but rather annoying. My chest also feels tight and there is a bit of a sharp feeling when I take in a breath. I don't have heartburn, as I don't have any burning sensation in my chest area. Any ideas what this could be. About a week before this started, my throat was sore but I thought I had a cold coming on because I was coughing and had some green muccus coming out. This eventually went away.
