FEVER BLISTERS
It is not at all uncommon for small children to develop a group of fever blisters on the lips when suffering with any disease, or experiencing a high fever. Even a simple cold or a spell of indigestion may be accompanied by fever blisters. They appear not only on the lips but also on the edges of the nose and may even be seen on the chin.
Early in their first appearance they may be treated with spirits of camphor or plain alcohol, which sometimes tends to abort them; but they usually run their course, and when they are fully developed they may be treated with zinc oxide, simple borated vaseline, or ichthyol.
