Hi, I have been experiencing sharp chest pains in the left side of my chest, and back. The pain is running to my shoulder and down my arm (left side as well). I am also feeling nausea, and headaches. It has been happening since last night. I tried to sleep it off, but it came back worse today. I was sleeping in front of a fan because I kept heating up, and it made me sweat alot more. The pain is making it really hard for me to breathe, cough, laugh. I was also experiencing pain in my entire body yesterday, where it felt as if my whole body had been bruised, and it hurt to eat, and walk.
