I woke up around 1:40am with a pain in my heart area, like a sharp cramp. My left arm felt tingly, with presure on the underside of the upperarm. I also feel the pain through my back as though the pain speared thrugh.I felt a little light headed and nauseous. I got up, drank some water, but felt weak so I laid down again, elevating my upper body with several pillow to elevate my heart. It is now 9am. My left arm still feels the numbness and I can't make a tight fist and it feels cold. My heart still feels some pain. I'm 46, 151 lbs. Heart conditions run on my dad side of the family.
