Chest pulsation. Space left side?

My question is ; 6month ago i faced anxiety and panic attack and feel pulsations on all over my body like hand ; chest ; and throat . My all ECG and ECHO reports are normal but instead of this i have anxiety symptoms without feeling anxious . Some times i have heart palpitations a d taking beta blocker daily . Is it normal to feel heartbeat in fingers when placing it on intercostal space  left side ??? I feel pulse on my left chest intercostal space on lying down on bed and also feel intense pulse in fingers  when lying on left side .. Commonly called apex beat .. Is these phenomenon are normal my all reports are normal . My 5th rib is also bulged out to some up on left side  where i feel most pulse.. Plzz suggest .
