I am so very sorry to hear this
I certainly wish I could make it all go away - barring that I agree with some of the other posters- don't just take it for granted that this is a necessary evil of RSD.
Have yourself checked out for bowel problems- gastro- intestinal issues ; other neurological issues. I would definitely start with the numbing in the legs!!!
One thing , one issue at a time all of this does not seem so overwhelming so please just go on a bowel mission

..for now ...the rest will come in its time
Look how great Hippy is doing with the dicetel.You will find your way too.
just breathe deep and make a plan
Please be good to you and see if you can get this under control
One less problem is always good even if we do still have RSD to contend with !!!!!!!!!
Much peace and luck
