Gerd, allergies, and asthma?

[missweasley824]

I am an 18 year old girl.  I am allergic to something I don't know what so I started to take Claritin daily.  This whole thing began in mid-May with a feeling like there was a lump in my throat.  I went to an ENT and he used a scope and saw nothing.  I still had the feeling like there was something stuck in my throat and this was accompanied by gagging, dry heaving and vomitting up anything that I ate.  I was also constantly spitting this mucus-y, clear saliva out of my mouth.  I went to the ER one day because I threw up and felt like I could not breathe well.  They ordered a Barium Swallow which showed nothing except acid reflux (I had been on Protonix at the time).  I then went to see a gastroenterologist, explained my symptoms and he suggested post-nasal drip and to go back to the ENT.  The ENT said he saw nothing and gave me a prescription for Nexium 40 mg 2x daily.  Around this time I also switched to Claritin-D and began using a neti pot.  I had an upper endoscopy: nothing there.  Since then the feeling of the lump is better and the nausea has stopped.  I don't vomit anymore or feel the need to gag.  My throat still makes a weird gurgling noise sometimes and I still feel the need to burp.
For the past month I have also been expieriencing trouble with taking a deep breath.  Whenever I breathe I feel restricted: like I can’t get enough air.  It seems to be worse in the morning and at night.  Even going up the stairs I have to pause and catch my breath.  I am also coughing a little and constantly feel the need to clear my throat.  There is a pressure in my chest, it feels tight, whenever I take a breath and sometimes I feel a little dizzy.  When I cough though, I feel like I can't do it well.  I sometimes also get this pain in my chest that moves to my back around my left shoulder blade.  It also feels worse sometimes just after I eat.  Could it be asthma? or something else?  I also have been feeling very hot all the time and I get very emotional and moody.

Thanks for replying.  
To answer your questions:

Sleeping, I do fine in that generally.  It usually takes a while (sometimes an hour) for me to actually fall asleep so I lay there for a while until it happens.  Eating is fine too.  After the lump feeling started to go away I found that I can eat again with no problems although I am still losing weight (I've lost 10 lbs. since this whole thing started and I'm pretty small already).

As for enjoying life, yes I am :) I've got no anxiety in my personal life at all.  Just got done with my first year of college and going on a cruise next week.  Any stress that I have is because of these feelings I've been having for the past month.  

Claritin-D has been really good.  I think that its because of this that I've stopped having to spit the clear mucus out of my mouth.  And it helps my nose feel less congested.

I do yoga for exercise.  I think that maybe some of this may be me stressing out about what I'm feeling but I don't think its actually causing my feelings, I try to not let it get to me.

How are you sleeping and eating?

Many of your symtoms sound stress/anxiety related. Are you looking forward to anything, are you enjoying life?

Does the claratine actually change your symtoms?

I think everyone's throat makes a gurgling noise sometimes esp. after a burp or if you're air swallowing (anxiety).

Are you exercising?
