I had food poisoning...decided to throw up and get that shitty feeling out. I threw up, and then stood up and pulled my back out. The kind were you see on movies where I couldn't move.

I had to go to the hospital in the morning to have them look at it. 5 shots later, an MRI, physical therapy and what not I am stuck with a bad back.

Now needless to say...my back was already on it's way out and the vomiting just made me tense those muscles so much that it pushed it the rest of the way.
