What am I allergic to?

I had a trip to the emergency room last Sunday (a week ago) because I couldn't catch my breath and my mid left back was killing me whenever I tried to breathe. What a terrible feeling.  They ran lots of tests specifically testing my heart, and EKG (boy those are allot faster than they used to be), x-ray(no broken bones and lungs look good), lots of blood test. Everything turned out fine.  I was real glad about that but now I'm just in pain and confused.
So I go to follow up with Dr. Beitzel on Wednesday and he says that I have a wheezing in my chest and bronchial tubes and that I'm not asthmatic or have allergies but I'm allergic to something.  Not real sure what that means but he sent me home with an inhaler and scheduled an ECO for this Wednesday just to follow up.
  The inhaler was working like a charm until last night. Man it's back and it's bad.  The inhaler isn't doing much of anything so I've taken a benedryl.  I called Dr. Beitzel's office and he is on vacation this week so they directed me to the other Dr. and there is nothing available for today but that I can go to the after hours clinic which starts at 5:45. "But be there early..first come, first serve" I just don't feel like I can drive an hour there, wait for help then drive an hour home just for someone to tell me to take an extra hit of my inhaler.  So I've taken an extra hit of my inhaler.  No relief yet.  I have to watch the BB's tomorrow for Jayme so maybe when I'm at the hospital on Wednesday getting my ECO I will see if I can get some help....Ugh
