neurological and now cardiac type symptoms x 3 yrs

I'm a 29 yr old male,  5 years ago I started having chronic nasal stuffiness (dry), a mild pressure headache all the time, and some positional vertigo symptoms.   I always noticed that if I exercised, my turbinates would shrink and my headache would temporarily go away and I could breath good for a while.    

3 years ago, I woke up one day and my headache was severely worse by 100 times over, ever since then I've had a 24/7 dull headache

Then 6 months ago, I started having chronic heavy chest pain and palpitations,  and  lightheadedness almost all the time...along with fatigue and nausea all the time too.

Again,  no matter which symptom you're talking about ,  during and immediately after cardio exercise,  everything gets temporarily better, and  I can visually confirm my nasal turbinates shrink but soon after  re emerge with the chronic swelling.

Back around when the head pain got a lot worse 3 years ago, my nasal lining was quite inflammed, some heavy antibiotics helped the color a little, but did little for my symptoms.    

Although my stress test, brain scans, echo, EKG's, holters,  and many labs such as ANA and lupus screens are negative,   there most definitely is something wrong with me    

Do you think maybe I have some kind of vascular problem, or inflammatory issues of a chronic nature?  (though my SED rate i must say has been consistently 0 over the years),  I have been evaluated many times and have never had a grossly abnormal CBC or chemistry panel.  

One thing I can say though, since my cardiac-like symptoms have begun, I have no longer had any morning migraine-like headaches (but still the constant dull head pain persists 24/7)

Can you please help

I do not see any evidence of vascultis based on your symptoms. The swelling of the nasal turbinates as a cause of vasculitis? I know of only one type that can affect people in a similar way, and this is called Cogan's syndrome, but I am honestly not an expert on the rheumatologic disorders.
About the chest pain: you have had many negative tests ( EKGs, ECHOs and most important Holters). If these symptoms persists one cost effective way to diagnose the cause of the lightheartedness is with a temporary implanted device ( Medtronic Reveal for instance) which an monitor your heart rhythm over months to years. If the symptoms are positional then a tilt table test can also be useful.
