One of the best ways to relieve pain and itching associated with an 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, take care with the amount of time applied, because prolonged exposure to ice can cause tissue damage, not to mention the overall sensitivity of the genital area.
