When I got home from work yesterday I spent about an hour on my computer. When I decided to go out for my run my lower back was really stiff. I managed to get a run in, but later it felt like I had strained something in my back. I did a few things to try to make it better, but finally decided that the best thing was to go to bed and sleep. I had a long strange dream, which when it started to repeat itself made me wake up, only to find out that it was an hour past my usual waking up time. I contemplated taking the day off since I was still a little sore, but went to work any way. It is still not 100% but is feeling better, so hopefully another nights sleep will sort it out.
