NSAIDs help reduce inflammation and alleviate pain associated with erythema nodosum, making them a valuable component of treatment. This approach addresses the symptoms that patients may be experiencing while the underlying cause is identified and treated appropriately.

In cases where the erythema nodosum is due to an infection, the primary treatment would involve targeting that infection specifically, which could involve antibiotics or antifungals, depending on the etiology.
