I Have A Problem With Feeling Weak And Passing Out

I have a problem with feeling weak and passing out sometimes. I have pains in my chest and it is often hard to breath. I sometimes cough up blood as well. When I do pass out my chest hurts and so does my body. From others that have seen me pass out say that I tense up and shake sometimes and look as though I'm in pain.ereshkigal2405@gmail
