A generalized rash is widespread, covers most of the body, or is
found on several parts of the body. It may appear in the same place on both
hands, feet, arms, or legs.
Many generalized rashes are caused by minor problems, such as dry
skin or
contact dermatitis, and occur after contact with soap,
detergent, or fabric. Many generalized rashes will go away with home
treatment.
A generalized rash may be a symptom of a chronic skin disease, such
as
eczema or
psoriasis.
Generalized rashes that are caused by a serious condition rarely
appear without other symptoms, such as pain or fever. It is important to
determine whether other symptoms are present and to evaluate those
symptoms.
Toxic epidermal necrolysis (TEN) is a rare but serious disease that
causes a generalized red rash. The skin involved in the rash may peel away,
leaving extensive areas that weep or ooze fluid, similar to a severe burn.
Medications are the most common cause of TEN.
Toxic shock syndrome (TSS) is an extremely rare condition. An
important symptom of TSS is a sunburnlike rash that develops within 2 days of
the beginning of a fever
102°F (38.9°C) or higher. Other
symptoms may include a headache, muscle aches, sore throat, vomiting, diarrhea,
stomach cramps, profound weakness, confusion, and signs of shock.
See your health professional if you have a generalized rash that has
not improved after 2 weeks of home treatment.
