questions about my symptoms

[addictions101]

i am a 29 year old man who is 5'10  245 pounds, i went to a cardiologist about  my symptoms,  which are   a heavy and tight feeling in the middle of my chest up to my neck, which makes me feel tired and weak, and hard to get a refreshing breath of air.  I also get heart palps in this same spot, most of the time they are post-exercise palps but not always.      Sometimes I'll have a good day, or stretch of days when my chest isn't too tight, I have my energy back and I can breath really good.   But some days are so bad that I have a hard time even wanting to leave the house because of that and I'm so lightheaded constantly.    
There has been at least 3 occasions where I thought something bad was about to happen because I felt so weak, my heart was squeezing too hard, and I got very pale and clammy and nauseated, but it always passed.
Before all this started about 5 months ago I had a few occasions where I had a very uncomfortable yet vague pain that traveled around my chest/neck/upper back.    
The tests I've had have been nuclear stress test, echocariogram and xray of my chest.  And my labs were also normal.
There's a couple of things I was wondering...why did I not get a stress echo, should they have done this?   Since my other tests were all normal,  what should I get done now because this is def. not normal in any way.    
I will be doing an event monitor starting in a few days, but what else besides that should I get tested for?
I have though that if anyone can figure this out it would be a cardiologist, pulmonologist, or endo doctor in that order.  Should I see anyone else?

Anything u can add would be appreciated  thanks.
PS--Isn't constant or chronic lightheadedness a good indicator of heart problems or impending ones? especially since my labs were all normal?  I am just so lightheaded allll the time along with my other symptoms.

If your echo is normal I would think that the nuclear stress test would be as good as a stress echo.  If your cardiac tests are normal it would be reasonable to ask about sleep apnea as it can cause some of your symptoms.  If your workup is negative you need to get into a good exercise program to gradually increase your activity.
