Hi, So I went to the doctor today because over the last week I ve felt a little light-headed and dizzy and I ve had some shortness of breath and fatigue/weakness. My blood pressure, complete blood count , and thyroid were all fine. She also ordered an EKG and a chest xray. She said that there was a calcification on my chest xray but it was probably fine and she hasn t gotten the EKG results yet. I m kind of worried about my heart now because of the urgency with which my doctor saw me and the number of tests I had done. I haven t really ever been that unhealthy before although I do have a family history of heart disease , but at seventeen? Do any of you have any experience with these symptoms and with the calcification on my chest x-ray? I am 5 9 and weigh around 130 lb.
