Angina?

How rare is it for a 26 year old woman to have Angina? I've gotten 2 EKGs done, a blood test and an ultrasound on my leg to rule out blood clots. My D Dimer was completely normal, as was my xray. Would they have seen severe heart disease on any of those tests? My anxiety/stress is absolutely through the roof. I havent slept in 2 days...maybe a total of 4 hours. Last night I was laying flat with my cervical neck pillow, I was awoke by 2 sharp pains in the left side of my breast, closer to my chest. Accompanied by that, my arms both got extreme burning right down to my wrists. My face, head, neck and legs have also been going tingly with burning sensations. I've been having gas pains in my lower abdomen, along with a lot of burping. I did get a diagnosis of GERD, which people say can be exactly like Angina or a heart attack, but my Omprezerole isnt working for it, the ER wont do any other tests on me because I'm "too young" for clogged arteries. The pain in the left side of my chest is mostly closer to my arm pit. The pain lasts for about 15-30 minutes usually, then subsides....but the burning comes back not even that long after the pain subsides. I dont see my primary care dr until Wednesday.
