Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain and give you my opinion. 
You should know that typical heart pains have some characteristics. They usually are retro-sternal pains like squizzing, tightness or heaviness. They may irradiate to both arms, neck and jaw and last from 5-20 minutes.It is posible to feel 
tachycardia, difficulties in breathing deeply, 
dizziness, nausea. 
 Pains that last all day long are not typical heart pains. 
Sometimes stress might give a little 
high blood pressure and a 
chest discomfort. 
Even though, if I was your treating doctor I would recommend some examination to feel shure that every thing is all right. 
I will recommend an electrocardiogram, a cardiac echo to evaluate heart function and walls, a full blood analyze whith cardiac enzymes and if it is possible a 
stress test and a holter pressure monitoring. 
After all this we can be shure for everything. 
So I will advise you to stay calm, it doesn't seem to be something to worry about but just make an appointment to do what I mention above. 
Hope I was helpfull. 
Best regards, Dr. Ervina.
