Now I'm a Victim of This.....:(

Wow, I really hate this and reading all the post, seems no one or doc can figure this out? I have all of the above and sort of nail it down a tad bit. First of all campbell's chicken noodle soup gives me allot of relief for about 4 to 6 hours no idea why. The doc says its acid reflex so put me on prilosec but I knew it wasn't acid reflex because I had it years ago. Didn't help a tad bit.
Now before this happen I just started my allergy shots was about 2 months into it, and also was on flovent hfa 44mcg, astelin, fexofenadine and nasal decongestant pills oh was also taking zantac150 pills. Once this tightness and gag feeling came I drop and stopped everything except the fexofenadine pills. I still got all the tightness, and have no problem breathing just that feeling of choking, that starts near the shoulders and up to the jaw area, but have no lump like others, ect... But when I got on the computer and started gaming, it gets intense and my neck just frooze up big time had to lay down and think different (total scared of course) woke up was a bit better. The systems have to be from stress or anxiety but I been gaming for many years and nothing I been doing has changed. I not sure if the allergy shots (since they go up in dose little at a time) cause this but I won't know for I stopped them a week ago. Guess I have to wait till it's out of my system to really get a clue on it.
Now for the last 3 months I had this pain in my hip left side but no exrays, mris, or bone scans could find a thing yet to this day (not sure if related). But up to my neck again something did trigger it, but just like you all I don't know what and again I don't know how to stop it. The doc wants me to see a throat doc and i'm somewhat against this because it had nothing to do with the acid reflex that he thought it was. I really don't want to go around to different doc's because in this day and age docs have to be careful and I do believe they care they just won't admit they don't know. I just a complete physical and I am in perfect health. This has to be some sort of anxiety mind related cause, but just so impossible to catch it.
I hope that someone has a cure about this and please it you get better come back here and tell us. I want to find an answer like all you do. I'm 38 at 140lbs always been this way never changed in weight or health just allergys. Could the allergy shots triggered this or a simple pain in another part of your body cause this or just a simple neck strain that ain't healing up right?
Lost as you all are, please help
