Jimmy,
 
A while ago, you mentioned waking up in the middle of the night and your throat was closing up.  You said you drank hot water to sooth your throat.  This same thing has happened to me.  I have had swelling in my throat for about six weeks, along with ringing in my ears more recently.  Then a couple of nights ago, I woke up with swelling bad enough that I went to the EM.  The doctor thinks I may be allergic to sprays or candles or something.  So I remembered your post.  Of all the things I researched, allergies didn't come to mind.  I wanted to let you know.  Hope you're feeling better.
