Erythema nodosum

Erythema nodosum (say "air-uh-THEE-muh noh-DOH-sum") is a condition in which red, painful bumps suddenly appear under the skin. They usually appear on the shins, but they may also appear on the ankles, calves, and face.

This condition can be caused by a number of diseases and infections, or it can be caused by medicines. Sometimes there is no obvious cause.

It often starts with flu-like symptoms, such as fever and aches. Sometimes these symptoms come before the rash.

After about 8 weeks, the bumps turn bright red or purple and then fade to yellow or green, much like bruises. The color changes in the skin may take weeks or months to return to normal.

Treatment is often not needed. But your doctor may do tests to try to find out what caused the problem.

Due to the threat of the COVID-19 (Coronavirus), we are taking precautionary measures to protect our staff and patients. We are implementing a temporary NO VISITOR policy at this time. Only patients or patients and their guardians will be allowed into the office. Please note, this is not to inconvenience anyone! The virus is a very real threat and it is essential that we stay healthy in order to provide needed care for our patients. If you are sick, we ask that you CALL the office to speak with a nurse before you come in. The nurse will provide specific instructions for you. Please DO NOT enter the office if you are sick (upper respiratory symptoms, fever, cough, or flu like symptoms). We are closely monitoring the situation and will update you as circumstances change. Thank you for your understanding!!
