I am a 15 year old female, and for the last year I have been have these strange symptoms such as: fainting 3 times in the shower, collapsing when I got dizzy, 1 bloody nose and it was my first time, headaches, dizziness and the room is spinning and I would have to lay down to regain myself, night sweats, abnormal heart beats, shortness of breath, protein in urine, chest pain, back pain, nausea, blurry vision, and some other symptoms not listed. Ever since I was a little girl I had bad stomach pain and the doctor just thought I was allergic to food, then later on I outgrew that. When I started fainting that's when I went to the doctor and they said when I stood up my heart beat was so low that I should have passed out. I had to wear a heart monitor and press it when I felt the episodes, but in the end they just said it was normal for me as if someone passes out in the sight of blood which is not the case. They had me go to a kidney specialists and see why I had protein in my urine and in the end they just told me to drink more water. Soon ill be going to a neurologist and a ear, nose, and throat doctor. None of my parents sides has problems only high blood pressure, diabetes, and something else. Any ideas about what could be going on with me and further testing I need to pursue? Thank you for your help.
