I didn't sleep well because my back was bothering me. It hurt all over. I woke up this morning to back spasms. I took 4 ibuprofen, and a hot shower. When I go to squat, it feels like I'm going to fall over. So I'm going to take it easy. I have two 12 he shifts sat and Sun. I don't want to make it worse, hurt myself or one of the people I work with.
