It can be difficult to resist, but try not to scratch the chickenpox spots as this can lead to scarring. Keep children's nails short to minimise the damage from scratching. You can help relieve the itchiness by keeping your skin cool-wear light clothing and bathe or sponge your skin with tepid water. This will also help to reduce a high temperature. Adding half a cup of bicarbonate of soda to a warm bath can be soothing.
