Heart issue or not

[Coophouse]

I have had 2 incidents where I suffer severe left underarm underarm pain, going down arm with some chest discomfort,sweats ets. First time troponins raised at 44 second time lower at 21. Ward Consultant said a Myocardial perfusion stress scan in December showed heart pumping fine.

He couldn't explain why I'm getting these symptoms.

I suffer long covid and a group member suggested that I should enquire about microvascular angina.

Would the scan not have picked this up, if it's heart related I want to know so I can adjust to lead a healthier lifestyle

Any answers
