Erythema means a reddening of the skin. If the condition is localized to one part of the body, this can be a sign of inflammation, irritation, or infection of the skin. Erythema over a joint can be a sign of joint infection. When erythema is spread over most of the body, like a rash, it is usually a sign of a generalized process such as allergic reaction, viral or bacterial infection or immune system disease.

The cause of your condition is not clear. Early in an illness, it may be hard to diagnose the exact cause. More time may be needed before a diagnosis can be made.

Home Care:

  • Watch for the appearance of new symptoms and report these to your doctor.

  • You may use acetaminophen (Tylenol) or ibuprofen (Motrin, Advil) to control pain, unless another medicine was prescribed. [NOTE: If you have chronic liver or kidney disease or ever had a stomach ulcer or GI bleeding, talk with your doctor before using these medicines. Do not give aspirin to anyone under 18 years of age who is ill with a fever.]
