I tend to disagree regarding lipitor, statins have potential myopathic side effects with striated muscle
One thing that many people don't consider, the diaphragm is skeletal muscle, statin myopathy effecting the diaphragm can cause many of your issues.
Another thing that is often forgotten, while statin myopathy is most commonly described in the literature as effecting skeletal muscle, Myocardiocytes(heart muscle) are also striated muscle. It's not impossible that the lipitor is causing or at least potentially playing a roll in the issue.
The "I think you popped some blood vessels in your lungs/chest and thats why it hurts" diagnosis, is quite frankly, bull****. IMO
a negative Chest CT wo/w contrast rapidly rules that out, rapidly rules out aortic aneurysm, rules out PTE, rules out any MSK related issues as well(save some soft tissue injuries that are highly unlikely to fit both your initial presentation and continued issues).
Printzmetals, while yes it is on the differential, given the history it does not fit very well unless he was doing a line of cocaine before each incident(stimulant induced printz). Printzmetals rarely occurs with exertion and the prototypical presentation is someone that has angina at rest and is not incited by exertion. To make the diagnosis you either need an ekg(not super sensitive but less invasive) on while symptomatic that shows the characteristic changes of ischemic myocardium or ct angio(considered the gold standard) while you are symptomatic(anyone that says otherwise is uninformed or giving you the run around). Printzmetals often does not have any elevated cardiac enzymes after an episode and the absence of which does not effect the probability of printzmetals.
Another potential but far fetched differential is a pheo. the test for that is fairly simple. they just measure urinary metanephrines/vma etc after a recent attack.
Pheo is a neuroendocrine tumor that can episodically release epi/norepi into your blood stream and cause a rapid increase in heart rate and myocardial oxygen demand, cardiac ischemia can cause the pain running down both arms. The vast majority of Pheo's are located in teh adrenal glands on top of your kidneys and are a very easy surgical removal. the caveat to this one is, the pheo does not have to be large enough to be visible on CT in order to be symptomatic. The second most common place for one is the organ of zuckercandle just inferior to the aortic bifurcation.
And do not take this the wrong way, but generalized anxiety disorder is a potential as well with what info I've been given so far. These could very possibly be panic attacks you are having as well.
Hopefully this is helpful and your physicians are able to figure out whats ailing you, medicine is a collaborative sport.
