It has been two months since out of nowhere, I started having breathing problems. I couldn't breathe properly. Since then, I have stayed two nights in the hospitals, have been seen by a multiple of doctors, gotten x-rays, echographies, urine and blood test, and so much more that I just don't remember. I feel like what is happening to me just gets worst and worst. Now, when my breathing attacks come, (a few times a day and lasts around an hour) I know how to manage it well but, along the way, I have experienced a ton of other weird symptoms. Dizziness when I stand up, throat tightness, random stomach aches, headaches, tingling sensations at the tip of my fingers, my eyes and arms start to twitch and slightly move by itself, like something is stuck underneath and needs to come out, and my legs hurt. I have seen a multiple of doctors but no one has identified what I have which stresses me. I'm only in seventh grade and I'm a bit scared of what has happened to me so far. Doctors thought it was a heart problem, which they tested, and said there was a slight problem but it was so small that it couldn't have been causing this problem. They thought it was a hormone problem (which they also tested for and came out clear). It annoys me that no one knows because it's been two months since I haven't been feeling like my normal self. When one of my symptoms appear, I try to ignore it and relax but it doesnt help. It comes at random parts of the day. Doctors thought it might just be growing up pains. I know It's not. I have asked so many of my friends and they haven't experienced it. And It doesnt feel like growing pains. Now they think it's anxiety but they're not sure. I dont feel stressed or depressed. I have a great life with awesome friends and a loving family. I don't know what's wrong nut I need to find out. Please help
