An<unk> .<unk> es may occur in any kind of tissue but most frequently within the skin surface (where they may be superficial pustules known as boils or deep skin<unk> es), in the lungs, brain, teeth, kidneys, and tonsils. Major complications may include spreading of the<unk>  material to adjacent or remote tissues, and extensive regional tissue death (gangrene). The main symptoms and signs of a skin<unk>  are redness, heat, swelling,<unk> in, and loss of function. There may also be high temperature (fever) and chills. If superficial,<unk> es may be fluctuant when<unk> lpated; this wave-like motion is caused by movement of the pus inside the<unk> . An internal<unk>  is more difficult to identify, but signs include<unk> in in the affected area, a high temperature, and generally feeling unwell. Internal<unk> es rarely heal themselves, so prompt medical attention is indicated if such an<unk>  is suspected. An<unk>  can potentially be fatal depending on where it is located.
