question: i have been experiencing severe tightness and pain in my left arm and left breast for almost 8 yrs...the pain happens around my period either before or after. i have had 3 ecgs in this whole period and each was normal. during the attack my bp always comes normal and once was even low...i am at the end of my ether here as every time it happens i think its heart attack but now after all these years it seems like the boy calling wolf story...but i still worry as i don't want to die in my sleep...please help it just doesnt want to go away....
