yesterday and all last night my heart was pounding in my chest like I was out doing excercising and I was just sitting most of the evening with friends. I have palpitations now and then but this lasted for hours and I was so worried I couldn't sleep till the wee hours. Is this just all anxiety that's physical or is it something else, does anybody else have this last for hours on end it is very troubling and scary plus now today my chest is a little sore from all the pounding I guess...just need to know if anyone has been there...god bless
