I'm gonna get my back x-rayed again cuz of my trampoline accidents when I was a kid. The doctor said that at this age it might be a problem. I don't care as long as I'm not paralyzed but I fear that because of spina bifida which i guess is a hole in my spine but it got covered up because my mom eats healthy. I can crack every vertebrae except the one I did in yoga at the hospital that I forget how to do. It's starting to hurt so I'm taking Advil. I also pulled a muscle in my neck really bad reaching for the alarm clock and a drunk guy jumped on me as well. I don't think it helped that I was still running and playing sports while it was healing..
