Those injuries do drain.

Last week I was running and I felt so fatigued. I did an inventory of my muscles and there was no one to blame...my lungs ached, but my lungs always ache...I had the faint awareness of a burden on my back, between my shoulder blades. That's when I remembered that several days before I had injured my back while lifting the third five-gallon bucket to the mouth of my fish tank. I felt the crunching sound you hear when you get adjusted at the chiro and I felt it cracking—not good. But afterwards, I forgot about it because it didn't hurt. This was an excellent experiential reminder that injuries impact us even when we don't feel pain afterwards.

Five days after the injury I went to my chiro appointment and was adjusted. I forgot to tell the chiro about my back injury (again because I wasn't feeling pain) but he found it. It made the same sounds and had the same feeling as when I injured it. But now it was back in place and my energy has improved.
