Bruce you can get a product at the pharmacy called zanfel. It is a special soap that will keep the rash from spreading and will remove the itch. It will also help to dry the rash up. It is the best treatment I know of and is not painful except to your wallet. A one ounce tube will run you about twenty bucks.
That's stuff does help, but only temporarily. Zanfel is approximately the same cost as a copay for a doctor to shoot you up with steroids (Prednisone).
Within a day or two the rash starts subsiding and within five days its pretty much gone. I've had to do this twice in the past ten years.
