I struggle with anxiety and stress, and have palpations so I knw what those feel like.But now I have felt this wierd feeling in the upper left of chest. It kinda feels like muscle twitches or fluttering, the problem is .Is that it's happening when I'm half asleep, so I'm not really sure how to expain,because I'm half awake and half asleep...I have had a recent cardo.work up recently and all and dr.says besides the "blurps" that shows on the bottom of my ekg all else it ok....I dnt feel it is....anyone else have this with their anxiety? If so how do you talk yourself out of it being heart related? And how to convene myself it's just anxiety???
