Description
Erythema nodosum is a raised, red, bumpy rash that usually involves the front of the lower legs. It is often associated with certain infections (streptococcus, coccidiomycosis), drugs (birth control pills, sulfa medications) and diseases (sarcoidosis, Crohn's disease, ulcerative colitis). It can also happen during pregnancy. At times no cause is determined (idiopathic). Most cases resolve within eight weeks. Women are affected more often than men and it occurs most frequently in patients between the ages of 18 and 34.
