The back pain I 'd been joking about a few days ago became no joke yesterday . I hobbled home from work early , and by the time I got home I could n't even stand upright . The pain was so bad that I was sweating and gasping .

Question: What could have possibly caused this back pain I was experiencing ?
Answer: It is because I joked about it , that jinxed me !It was from sitting around doing nothing .None of the above choices .The sweating and gasping made the pain even worse !
