Okay, also with all of your comments some of these got me thinking back to when this first began, here are some other things, about a month before the throat started, I woke up one morning, and well I don't know if any of you have ever had a nerve twitch a couple of times in your eyebrow?  Well I had a twitch like that only it was in my eyelid, and it didn't last a couple of seconds, it lasted a few days.  When I consulted my doctor he said it was stress, related to these blinding headaches I had been getting for a couple of weeks prior to called tension headaches.  All of that went away, and about a month later came this feeling in my throat, at first I thought it wass just a tightness like when you get upset, then it became so annoying like a lump in my throat, even feeling like my throat was so dry.  Well one night panic hit me when I felt like I couldn't swallow at all.  I went to the emergency room, and was there for hours, being tested for my thyriod, and a ct scan, which all came back good.  They suggested I go to my doctor for acid reflux.  The very next morning I awoke with a locked jaw!  My jaw would pop, and shift before I could half way open it.  This continued for five days or so, in which time my tongue felt swollen, my teeth were imprinted in my tongue, when I awoke.  I also brushed my tongue, and felt like I brushed it raw. This also passed given a few days.  I was simply left with this feeling in my throat.  It never goes away, it does however get worse when I raise my voice or get stressed with normal things, and yes when I eat or drink I don't really feel the lump, its when I swallow my own saliva, and yes when my tongue swoll I felt like I had way too much saliva.  Even now from time to time.  If it is Anxiety, it would make sense as I have a overwhelming fear of bad things happining.  I've had that problem since I was very young, feling as though if I didn't put things back in their proper place somthing bad would happen to my mom.(Crazy?) As the years have passed I've adapted to it or so I think?.  Also all the symptoms of Cricopharyngeal Spasm also seems so simular, and od course GERDS is still there?  So I guess what I'm getting at is does anyone have a better guess, or more able to narrow it down than me?  Still here.
