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 typical heart pains have some characteristics. They usually are retro-sternal pains like squizzing, tightness or heaviness.They migh irradiate to both arms , neck and jaw.Usaly last 5-20 minutes.
Pains that last all day long are not typical heart pains.They might be mucular, sceletic or neurotic pains.
So, my opinion is that you should not worry about your husbant but to be absolutly shure he can make a cardiac chek up.
If I was the treating doctor I will recommend some examination like a cardiac echo to evaluate heart function and walls, a full blood analyze and a strees test if it is possible.
It is also necessary to clear the blood preasure situation.We talk about
hypertension if we have mean value that exceeds 140 / 90mmHg.A person might have high value during emotional and physical strees so its mandatory to judge on mean values.
This examination might clear the sitauation even though I thing you shuld not worry, it doesn't seem anything serious.
Hope I was helpfull.
Best regards,Dr.Ervina.
