Hi, i am a teenager and i have a quite serious problem. I have a shortness of breath, it seems like there is something pushing my chest slightly. I can't take a deep breath. Sometimes, it seems like I can't breath at all. When that happens, i have a tingling sensation in my hands and chest. A few days before, the area around my eyes is a bit uncomfortable and a bit nausea. Then two days later, I had a sudden short of breath and i was admitted to hospital. They checked me with ECG and they said that at first, my heart beat very fast (130), but quickly returned to normal. The doctor said no problem with my lungs and heart. At night, i have shortness of breath again, so i went to different doctor. He said that I had gastrointestinal problem and the shortness of breath was caused by panic. However, I felt that it wasn't anxiety. He also said that mu heart and lung was clean. The next day, I went to another doctor and he said the same thing. The next day, i had another serious short of breath. I went to nose specialist and he said there was a little infection, however he said the shortness of breath was again because of anxiety. He gave me sleeping pills. Now, i had another short of breath and i didn't think it was anxiety. What happen?
