You MUST do the hot water treatment! It really works! It doesn't cure the rash but it definitely takes away the itch. You have to run hot water over the affected area and keep turning up the heat on the water until you can just barely tolerate it. Then just let the water run over the area for about 10-15 minutes. When you get out of the shower you will experience 6-8 hours of relief. What happens with the hot water is that it's actually releasing all the histamines under the surface of your skin. Histamines are the little boogers that send the "ITCH" signal to your brain. It takes them 6-8 hours to replenish. Therefore, you will do yourself a huge favor by submitting to the HOT water treatment. This doesn't cure the rash but it removes the itch while you are medicating the rash. I went through this about 5 weeks ago. The hot water treatment made me a believer.
