About a year ago, I started getting a sharp "stabbing" chest pain (or rather, it kind of feels like a pinched nerve, that's why I never bothered with it until today-- thought I was just sleeping in a bad position). It would come, stay for a day (or even just a couple hours, striking on and off) then it wouldn't come back for like weeks and I would forget all about it. Today, I had it on and off all day, accompanied by a "pinched nerve" feeling in my elbow so I went to a doctor. Got an EKG and they said it was normal except for one thing and showed me the paper. If I remember right, the V1, V2, and V3 (third column from the left, if all EKG printouts are laid out the same) was "upside down" where the doctor said it should be going "up". He said it was possibly normal, but wanted to do more tests (which I'm going to do, ofcourse). They also said it could be because of an energy drink I had yesterday, but I've -never- been caffeine sensitive in the past (then again, I may have been but never knew it). I'm just a bit worried and any info will settle my mind a lot.

Other notes... I'm only 20, Female, No history of alcohol or smoking, no family history of heart conditions, and have normal blood pressure and bpm. Other than being a bit underweight, I'm healthy and I'm not on any meds. If it means anything, I got bloodwork done (but it was like 3 years ago, maybe 4) and was told I have an iron deficiency. Since then, my diet's become more health-focused and I take vitamin supplements daily, so I doubt I still have an iron deficiency.
