Your doctor can usually diagnose this condition by looking at your skin and asking you about your family's medical history.
A skin biopsy may be needed to rule out other similar conditions.
Avoid triggers that can make your symptoms worse, such as wool, lanolin, and certain foods. Experts do not recommend taking frequent baths - excess bathing and soaps can cause dry skin, which often makes the condition worse.
Your doctor may recommend skin lotions, soaps, or moist bandages to soothe scaly, dry, or healing areas. Antihistamines taken by mouth may relieve itching.
Persons with severe symptoms may be given prescription skin ointments that contain tar, corticosteroids, or immunosuppressive drugs. In rare, severe cases, the doctor may prescribe more powerful corticosteroids to be taken by mouth or injection.
Nummular eczema is a long-term (chronic) condition. Medical treatment and avoiding irritants can help reduce symptoms.
Call your health care provider if you have symptoms of this condition.
Also call for an appointment with your health care provider if:
Symptoms continue despite treatment
You have signs of infection (such as fever, redness, or pain)
There is no known way to prevent the disorder. Avoid any triggers that make your symptoms worse.
