Hello and thank you for using HCM.I carefully read your question and I understand your concern. You should not worry.
I'll try to explain you something and give you my opinion.
You should know that chest pains might have different reasons.The origin might be cardiac, gastrointestinal problem, skelectic, muscular or neurotic problem.
You should know that typical chest pains has 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.
To exclude
ischemic heart disease, if I was your treating doctor I would recommend a strees test.
The fact that you have done aniography is a good thing and probably the situation is still the same if you have the same complains, but it has passed a lot of time so a strees test is necesary.
Ti exclude gastrointestinal problem you should do a gastrohepatologyst consulting and maybe a fibrogastroscopi. Gastic problems, gas presence, reflux or ulcers might be the cause of your symtoms.
Also you should do a thorax xray to exclude any sceletic problem.
Only after all this we can better understand what we are dealling whith and how to treat it.
Hope I was helpfull.
Best regards, Dr.Ervina
