Heart attack anxiety helppp

Havent posted here in a while , ive had anxiety for a really long time now about literally anything that could go wrong with my body, but as of recently for about two or three months now ive had panic and anxiety of having a heart attack, im 17 but I feel like thats no excuse for stopping one, i occasionally get pains or weird feelings in my arms , mostly left, small tiny chest pains (sometimes sharp or electric like and sometimes a crushy like feeling but they only last a second or two and fo away , and we'll I haven't had a panic or anxiety attack in a while so tonight I was really alarmed when sitting in the car talking with my dad about something and slowly felt a light warmth like sensation under my left arm , I started panicking instantly thinking H-attack as the feeling started moving up my left side into my chest then i felt like i couldn't breath panting quickly and tightening my arm muscles , i tried calming myself down by saying it's just another panic attack but I've never felt one that started in my arm before so after somewhat calming down i was still very alarmed by it and only thought of the worse temporarily making myself think it wasn't anything bad :'(

have you ever had a complete check up? For your peace of mind I suggest you do that. When it comes out normal results, then you know all of your symptoms are from anxiety and stress. And yes, anxiety can definitely cause the symptoms. I have happened myself many times. but it is definitely very rare for anybody her age to have a heart attack. So go get yourself checked out so you can get on with your life. If you have a history of anxiety and panic, I highly suggest speaking with a therapist who can help you manage this. This is difficult to go through alone and they can give you ways to manage it. there are many great meditations on YouTube for anxiety and panic that will completely relax you.
