My Panic Attack Solution

I’m personally a bit scared as of right now because I can’t figure out the difference between heart attack warning symptoms and panic attack symptoms. You see, I’ve been having a quick, sharp pain in my chest ever since I woke up. I woke up at 9:02 am central time. It goes away but comes back every hour or so. Now I’ve been trying to calm myself down and say it’s nothing but for a couple of days now I’ve been dizzy, my left arm has been having muscle spasms, my face has been feeling like it’s swollen, more or less meaning there’s a lot of discomfort, and now I’m having a pain in my left shoulder/ upper arm. Please, can someone possibly tell me what’s going on? I’m only 18, I shouldn’t be feeling like this, should I?

go to the hospital asap
