GERD (acid Reflux) :: Throat Swollen / Narrowed - Food Not Going Down

I have a couple of points I'd like to ask about here and any advice or pointers will be appreciated. The first thing is that my throat seemed swollen or narrowed in some way. It's completely painless, but I know at the same time that it's not normal, and my throat wasn't like this before. Swallowing even tiny vitamin supplements is unpleasant so I just chew them, because otherwise I have to force them down with lots of water. I've had tiny tablets get stuck in my throat before and I gag on them. I don't know why this is such a struggle for me when I see other people swallowing giant capsules with ease. With other foods it is creating other symptoms. For example, I just ate soup, but immediately afterwards I can feel soup in my throat that hasn't gone down. I brought it back up like phlegm, and pretty much a teaspoon full of pure soup came back up, a good minute or two after it was swallowed. Shouldn't that soup be long gone down toward my stomach by then?

Another feeling I get is this "bubbling" feeling in my throat and the middle of my chest accompanying the food not going down. A lot of air is coming back up whenever I eat, and I find myself belching constantly. A lot of the "bubbling" sensations I guesstimate are air coming back up and looking for a way around the food coming down. What can be done about all this trapped wind? Sometimes standing up causes it to rise up my chest through my neck and out my mouth. I can feel it traveling all the way up and it's a weird sensation. Throughout the day I'm almost constantly working air out of my chest and in to a burp.

I experience no real pain, or even burning / heart burn most of the time. Things just seem to come up a lot, whether it be air, food and very rarely, acid. Even on the rare occasions that I get "acid reflux" with acid in my throat, the first I know of it is when it hits the back of my mouth. Is that unusual? Shouldn't I feel "heart burn" or other symptoms first if it has managed to come up that far? I struggle to lay down after a meal because the food sits there in my neck and refuses to budge. It's starting to affect my quality of life because I'm having to carefully plan how/when/what I eat , when I lay down, how I lay down etc.
