Ok. I'm Really Concerned, 48 Hours Ago Now I Had

Ok. I'm really concerned, 48 hours ago now I had serious chest pain which did feel like a knife twisting which made me not be able to breath in without it hurting. I can't take a drag of a cigarette without severe pain in chest like an ax hitting my chest. Very bad chills and hot and cold sweats with a constant heart burn which in the past was due to my flap in my throat not working anymore, but this time it's constant and I just can't breath in fully and sure can't smoke. This happened instantly 48 hours ago when I originall had severe chest pain. I don't like Drs as I don't have insurance and they tend to just wanna get you out of there. I also must mention at 38 I damaged muscle tissue which dr said I had the heart of a 57 year old. I am now 44. Should I go to er or keep trying to wait for it to pass? Ty please help
