One of the best ways to relieve pain and itching associated with a genital herpes outbreak is one of nature's most basic miracles: ice. To reduce symptoms, apply ice to the affected area [source: Grayson]. Fill a plastic bag with crushed ice, wrapping the bag in material the thickness of a sheet. Apply for 10 or 15 minutes, and repeat several times a day. Make sure and discard any plastic bags after one use.
As a precaution, be sure you don't apply the ice for too long. Prolonged skin exposure to ice can cause tissue damage, and the genital area is especially sensitive.
