December is a month of many changes. It is the last month of the year, when expectations mount, and of course Christmas is another stress and joy factor in our lives, when we can finally spend some time with family, leave the work week behind and spend some time with loved ones and focus on ourselves and not our work.

Most of us will have to deal with cold sores at one time or another in our lives. Cold sores are small, swollen sacks with a ring of sensitive skin around it, usually appearing on the gums, on the inside of the mouth and cheek, or on the mucus membranes. The sore itself is harmless but unpleasant; it can become sensitive and turn into a scab, it can bother us when speaking, and can hurt when exposed to hot or cold, or spicy foods and carbonated beverages.
