I look at it from 10 feet away and I am covered. I am lucky and live on the coast and can get salt water - it is the best for drying it up. Pool water works too, but not as fast.
Aveeno has a bath soak - oatmeal based and just soak in it. I live in the tub when I have it. Have been known to sleep with white goves on so I don't itch it.
Have been told if you get those patches that "detox you" it will pull it out of your system.
Good luck 0 take alot of benedryl and sleep!
