First off prayer is the strongest medicine..I smoked 7 years of my life i quit 2 years ago,its was making my Gerd (acid reflux worse).Ummm im i can help you all i can on this issue because like you its my main concern..Mine started from that symptom yet,it still is my main fear..I cant conqouer because im afraid if i do,than maybe i will miss something when there is a problem there...
Symptoms for me went from a racing heart for months,and raised blood pressure,and had the resting echo,stress test,ekgs,and stress echo..IO guess im not worried about heart disease as such regarding my age im only 26..I think in the back of my mind its a rythhm probelem..its cost me days and now years of my life with this worry..
Latley the symptoms shifted more like a flip flopping heart deal,sometimes it feels like its racing when it isnt..just pounding crazy,or i feel tight in my left ribcage area..it just dosewnt feel like it working right..from books though ive learned this is normal..i cant conqouer it give me feedback on what you feel...hope this helped,prayers ..
