Replying to Back Injury Advice

I know that this is not the right place to be posting and I know that most people will say go to the hospital but I am wondering if anybody has experienced anything similar because I would really like to avoid going to the hospital. Alright so around 1:00 today I fell on my back pretty hard on ice, got the wind knocked out me and then started coughing up some blood. Didn't think that much of it rode for another hour or so and every now and then coughed up a little bit of blood (Im talking specks of blood in my spit). About three or so hours ago my chest started hurting and I am having a little shortness of breath to the point that I can't take a extremely deep breath but breathing is more or less fine. Another thing is my chess feels heavy, I know that is not a good explanation but its really how it feels and when I do attempt to take a deep breath there is a sharp pain under my sternum. So anyone ever fall on their back and get these symptoms?
