When i cleansed and my liver was blocked, i got rashes on my belly and back. It could be trapped toxins in your lymph system....if they can't get out through the normal channels, they can get clogges up anywhere. I read where lymph blockages clear by sweating back of neck, back of knees, feet, armpits, and I think genitals were mentioned too. I know it's true because when my lymph was blocked my feet sweated and they never do....and my armpits itched like crazy....it went away when the lymph blockage was cleared.
