Unexplained and rapidly progressing pain may be the first indication of necrotizing fasciitis. Pain may be disproportional to the physical findings; indeed, exquisite pain occurs at the affected site, so a finding of severe, excruciating pain that seems inconsistent with the observed clinical findings should strongly suggest the possibility of this diagnosis.

Erythema may be diffused or localized or may be absent. Fever, malaise, myalgias, diarrhea, and anorexia may also be present. Hypotension may develop initially or over time. Surgical exploration is critical for establishing the diagnosis and directing management.
