 If you're a trundler, it happens at least every five years. But if you miss a pothole as deep as the one I missed when I was watching the 15th Mrs. Hewitt Park, I went down, did the roll, and boy, it's a wrench, and that's what relieffactor.com exists for. The minor aches and pains. I didn't break anything. I haven't hurt. I'm going to do a long walk this morning to try and loosen it up. But relieffactor.com, twice today, that's what I do when I've got a minor ache and pain that needs to go away.
