2. Cold compresses are a good home remedy to use for postherpetic neuralgia.
The cold compress will reduce inflammation and itchiness of the rash. The cold compress doesn’t have to be freezing cold. If the water is too cold, your skin’s sensitivity will increase. The water should be just cold enough and place a clean washcloth into the water. Place the cold compress onto the rash and let it stay on the rash for a few minutes. This can be done a few times a day.
Instead of scratching the skin, get a cold compress and place it against the skin. Don’t rub the cloth against the skin when it’s itching. By rubbing it, it’s like you’re scratching it. The redness will start to disappear as well. The more times you place a cold compress onto the rash, the redness will go away. This can even be done when you’re out. Just keep a bottle of water and clean washcloth with you at all times.
