I don't think it will get better by standing up straight.
I just checked Andreas' book and it seems to come from dirty colon (mucoid plague). So finish doing your Oxypowder cure and then do the colonix.
Since Andreas books are copyrighted, I would suggest to get his e-book The Key to Health and Rejuvenation from www.authorhouse.com. It is $6.95, you can look up things by typing in prolapsed colon under search.
