I'm having a strange feeling in my mouth/throat, kindof at the back left side of my tongue, tonsil and throat area. I looked in the mirror and my tonsils don't look swollen really but my uvula was stuck to my left tonsil or side of my throat. I've been really stuffy and having nasal drip recently, which has caused heartburn. I've also had a sore throat on and off for a few days now. Any ideas as to what it is? I feel like I can breathe fine, I was able to drink water. The weird feeling just started like 20 minutes ago but it's bothering me, I'm afraid to sleep because of it (it's 5 am).
