Im quite young, but recently I felt stabs of pain in my chest that went all the way down to my wrist, which started throbbing and then I felt like throwing up, dizy and a little numb. My mom has complained all her life of having heart problems, could this be hereditary. Ive never had anything like this but a couple months ago I tried coke a few times. Obviously not a good idea, but Im wondering if thats the effect its had on me. Coke meaning cocaine, u dummy lol
