My ankle killed me afterward. I had been standing all day too and I think that had more to do with it than the walk.
I am having a flare up. It has been too long since I have taken care of myself. It is difficult to start again. I have to deal with the pain of post-exercise. I have to be very motivated to deal with that. I have such a headache right now. My shoulders hurt, my feet hurt. I have had some issues with sleep, and am not eating well. I have to motivate myself to go from here. So far, three days in. I ran on Tuesday, walked on Friday and a good bike ride today. I have had several false starts this winter. But Spring, and the new job will help.
