Lymphadenopathy can be moderately tender, with erythema and increased warmth of the overlying skin. Lymphadenopathy remains regional and typically resolves within 2-4 months but may last up to 6-12 months. Rarely, it may persist for a year or more. Approximately 10-30% of nodes may suppurate, requiring needle aspiration.
