I do the same thing. I start something, get excited and push when I know I should not, but REALLY want to make progress and then I can barely move for the next several days. Have to clean or anything else in short spurts. I hate it that I can't get more done. My brain has all these wonderful ideas and fun things to do and try, but my body just will not get with the program. I'm sorry you are in pain. I understand. Big Hugs.
