Salt Flush during hemorrhoid recovery? And can parasites cause or contribute to hemorrhoids?

I have never tried a salt flush. I guess it gives you a good cleanse and perhaps kills or flushes out some parasites at the same time?

The parasites that I know I have according to stool samples: Blastocystis hominis and Dientamoeba fragilis (many).

Not sure if they could be related to the returning problem with hemorrhoids (external and internal)

What i would like to know is if a salt flush is going to hurt? Salt in the wounds I guess will hurt (as the loose contents of salt comes out through the intestines?

And can the parasites somehow be related to the recurring hemorrhoids?
