What are good home remedys for outer hemeroids?

Soft stool & steroid. I would make sure you are having soft stools and not constipated. You may need to increase the fiber in your diet and consider miralax (polyethylene glycol). I would use baby wipes instead of toilet paper. Try to bath after bowel movements. If still having symptoms a short course of topical steroid cream may help.
Cold. Ice wrapped in a washcloth, and witch hazel to shrink and stop the itching.
