I am 31 years old, i have been having chest pain and severe lightheaded episodes with severe fatigue that last anywhere from 20 minutes to 5 hours. When I have these episodes it feels like the life is draining out of me, it feels like I'm having a continuious head rush or a low surge of electricity thru my head. I am incapacitated and the slightest disturbance makes it worse. I have also noticed that my chest pain, which feels like a squeezing or throbbing in the center of my chest and below the left shoulder, it now feels like i have deep chest wall pain in the when I move my arms in certain directions such as hold them directly in front of me I can literally feel tenderness in my chest wall without touching it, but when you press on my chest wall it isn't really tender. I am confused to the source of my symptoms, why if it's just chest wall pain then why the other symptoms that started the same time? Please help> I had a normal chest xray and echo
