Age is just a number, and it should never stop us from taking good care of ourselves.
As we get older, the skin becomes thinner and heals more slowly, so small problems can sometimes grow into bigger ones.
The back of the neck is a common place for cysts and boils, because the skin there is thick, oily and constantly rubbed by collars.
When a hair follicle or cyst gets infected, it can swell into a large, red and hot lump, often with a yellow head forming on top.
Sometimes several infected follicles join together under the skin. This is called a carbuncle, and it can be very painful.
