I am 15 and just last week I was accidently thrown into a wall. The upper right part of my back hit the wall first with an amazing pain that rushed after it. There is no bruising that I can see but I can not take deep breaths or regularly take breaths for the pain is to severe. I take short breaths and my right lung does not appear to inflate like my left lung does. It constantly has a burning feeling but I can be at most ease when I am not laying down or leaning over in any form. I have these coughing spells that occur infrequently that I cough and cough but I can not bring air back into my body. When I have finished coughing I feel like there is not enough air in my body and my pulse quickly increases. I begin to breathe heavily and I struggle to bring in air. The last time I had one of these I passed out due to not being able to breathe. My friend suggested that I have a bruised lung but I do not know anything about them. Suggestions or comments?
