Secondary erythema nodosum presents as tender erythematous nodules on the lower extremities. The condition is generally self-limited and follows a predictable resolution course when appropriately managed.
The treatment target is resolution of the tender erythematous nodules on the lower extremities, expected within 1 to 6 weeks as lesions evolve through the colour changes characteristic of healing inflammation.
First-line management relies on symptomatic support: physical measures directed at localised edema and discomfort form the foundation, with non-steroidal anti-inflammatory agents used for pain control. The full structured protocol — including the specific options and their application — is available via the link below.
Symptomatic support is an adequate approach for most patients.
Compression bandages and limb elevation may be used for edema and pain relief.
Non-steroidal anti-inflammatory drugs, such as indomethacin at 100–150 mg/day or naproxen 500 mg/day, may be used for pain control.
Erythema nodosum is generally self-limited and resolves within 1–6 weeks by turning from a bright red to a yellow–brown or green-bluish discoloration, resembling bruises.
