I was coming out of an elevator yesterday and apparently it did not level out. I went to exit, tripped and fell right knee first onto the floor. My knee was bleeding on the out side, a scrape and it did hurt, my upper body nothing. Now today, the swelling has signficantly gone down in my right knee, but now my upper body on the left side in the back and under arm area hurts and I fell on my right side. Can a fall like that cause a person to fell pain all over even if they fell on one side of their body?
