Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain you something and give you my opinion.
You should know that heart pains have some characteristics. They usually are retro-sternal pains like squizzing , tightness or heaviness. Theymay to both arms, neck and jaw. They last from 5 to 20 minutes. They might be associated with
nausea,
tachycardia, difficulties in breathing deeply,
dizziness.
But, heart pains might be also atypic, meaning that they do not have the upper characteristics.
As you previously had
stent it means that you suffer from coronary
artery disease and you are at higer risc to have problems again thith you arteries or the stents that you have.
As you explain, your simptoms are not typical for heart pains.Even this it is necessary to make some examination.
If I was your treating doctor I will recommend a cardiac echo to evaluate heart function, a full blood analyze whith cardiac enzymes and if it is possible a
stress test to exclude active coronary artery disease.
After this we can be shure if it is something to worry about or not.
Hope I was helpful.Wish you good health.
Best regards.
