Hello,

I see you are asking "What is erythema nodosum?"

Erythema nodosum is characterized by tender, red bumps, usually found symmetrically on the shins. Up to 55 percent of cases have no clear identifiable cause. Sometimes, erythema nodosum is not a separate disease. Rather, it is a sign of some other infection, disease, or of a sensitivity to a drug.

Erythema nodosum is an eruption of tender red lumps on both shins and occasionally the arms and face. Bruising often accompanies the nodule formation.
