I think sore throat and enlarged uvula are two separate issues, in my case at least.
This is what definitely happened to me.
-I do have a snoring problem (to the point it worries my wife that I'm not breathing.
-I do have allergies. I take Zyrtec daily and Mucinex D when its worse. I get sore throats from this constant dripping. I also snore because I have difficulty breathing through my nose.
-I also have acid-reflux
This past weekend we went to a three day Country music festival. To say the least I consumed at least 3 cases of beer, plus some, from Thursday to Saturday night.
-Thursday night I slept on the ground outside in a sleeping bag. it got cold in the morning.
-Friday night I slept on an air mattress, but was unable to sleep on my side, and was actually surprised I slept so well sleeping on my back due to snoring which usually wakes me up at night. Saturday morning I woke up with the feeling that a chunk of the roof of my mouth was hanging down. I looked in the mirror and saw my uvula hanging down clear to my tongue. It almost looked paralyzed. I had to hang my head to left or right or forward or extremely backward to swallow. There was no pain at this point.
By the end of Saturday night I was starting to get hoarse and a sore throat. My throat was red, my uvula had a white film on it and a lump on the upper right. Sunday morning woke up with sore throat and feeling like i was going to choke on my uvula. I was also having drainage problems from allergies that was irritating my throat. And the same Monday. Monday night I played in a poker tournament and noticed that the sore throat and uvula problem was helped by drinking and soaking back of throat with cold salt water. today is Tuesday and I still have sore throat and and read the previously posted forums. The salt and pepper coating on my uvula definitely helped the uvula. I do intend to get some warm salt water to gargle for the sore throat, which I believe is caused by the sinus drainage as I've had this problem before. I just don't have any Mucinex D to dry it up to stop the irritation. BTW did anyone watch the suggested video below "Learn about your Uvula" it was an excerpt from Dr. Oz show. they actually scope a woman's throat to show the uvula and then scope her nose to watch her swallow applesauce. It was kinda cool and gross at the same time.
