hi , i am a 29 yr old female 170lbs i have been having strange chest pains and hearlt papltations for the last few years with recently them getting worse i have had an echostress test some xrays and ekgs and all have came back normal but im worried about how simple tasks liek bending over or sitting up or what not makes my heart pound like crazy and it also feels as if it flops or a popping feeling in my chest also sharp pains in my throat and and tingling tight feelings on both sides of my arms with dizzyness. i have also let my pcp know that i get randomly through out the day this feeling as if my air cuts of or as if someone is choking me this senstion lasts about a few seconds. my bp has never came up as an issue but once ofter kindney stone removal . have tried anxiety meds but have not found one that helps. i would really love some help as this takes up so much time in my life constantly worrying. thank you
