I am 27 years old. I am a female..  Last nite i had extreme chest pain on my left side where my breast is, It was sever sharp and stabbing. It also pulsated through my back. It came on lightly last nght and then hit me severerly fast. I ended up getting on my knees rocking back and forth doing all I could from screaming in pain. The pain was definitly a 10. It last for about 25 minutes in the highest pain, all together maybe lasted 45-50  minutes. The pain was worse when i would take a deep breath. My left hand started to hurt and get numb when i had the worst of the pain. I also had a headache. I am still in pain in my chest and back but just aching pain. I feel very weak and tired since all of this and lightheaded as if things seem slow to me.  I am curious what could of caused this
