Those are classical heart attack symptoms. Did you go to a hospital and cardiologist for a cardiac work-up? If not, I urge you to do so ASAP. Don’t delay!
Yes, twice. No heart attack or clots. EKG, labs, chest x-ray, they did a sonogram on my neck, a stress test, next is the nuclear test. I take my BP (which has been elevated after each episode but goes down to normal a few hours later and they have ordered a heart-monitoring vest.
I have a team working to figure it out: my general doctor, a pulmonologist, a cardiologist, and a neurologist.
This year, Santa gave me coal in my stocking and a stack of medical bills.
