But it is best to know as it can build up
in your mind until you know.
i did not have the intense pain
in the chest.It seems that this is the deciding factor.A anxiety attack can have simular symptoms ex arm pain dizziness upset stomach elevated pulse. I have been into weight lifting for a long time and i realize that my pain came from the intercostal muscles between the ribs.Also my pectoral,chest, gives me pain but this is muscular.
