PE sufferers!?

hi... Im starting to develop a fear of PE, since my chest pain was cleared from me thinking I was having a heart attack. pain is still here. alot of burning pain. Im super scared and not sure if I need to be seen or if its just my anxiety looking for another scary thing to worry about!! pain won't go away but does come and go. Im not short of breath and it doesn't hurt to breath, yet.... so its just the pain. anyone who had PE.... what where your symptoms?? and how were you diagnosed??
