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 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. They last from 5 to 20 minutes and may be associated with
tachycardia, difficulties in breathing deeply,
anxiety.
Pains that last all day long are not typical and usaly are not related to heart.
Felling tired might be related whith a lot of patologyes like problems whith heart function,
anemia, electrolyte imbalances,
thyroid gland problems.
In my opinion you should not worry about.Your symtoms are not related to heart problems.
Even though, to definitely know what is the problem if I was your treating doctor I will recommend some examination like a cardiac echo to evaluate heart function and walls, a holter rhythm monitoring to evaluate heart rhythm, a strees test to exclude
ischemic heart disease. A full blood analyze to exclude anemia, thiroid problems or electrolyte imbalance.
Only after this we can better understand what we are dealling whith.
Hope I was helpfull.
Best regards
