I am a white 34 year old female, non-smoker/never smoked a day in my life, and rarely drink. I went to the ER Friday evening/Saturday morning because I had chest, arm, and back pain. They drew blood, did an ekg, and an xray. They came back normal, and diagnosed me with GERD and torn muscles in my upper back, and muscle strain in my elbows. I believe I've had GERD for most or all of my life, but without the heartburn. I never realized what I had.
