I'm a 28 year old female. I've had chest pain for the past 9-10 years. Always on the left side and radiates to my back, left arm and abdomen sometimes. I've got ekg's, chest x-rays and treadmill tests done often and it always came back normal. Except for my LDL(cholesterol levels) which was elevated. The doctor suggested change in diet and all the ones i've gone to have told me the pain is "probably" not cardiac. Should I be worried? I feel a little dizzy and sluggish sometimes when the pain comes.
