Necrotizing fasciitis (NF) is a real bad deal. We usually rely on clinical exam (which can be misleading) or other imaging studies (which can take forever) to make the diagnosis. POCUS would be an awesome solution in helping to make this time-sensitive determination. We know it can pick up fascial fluid, air, subcutaneous changes...but really how good is it when it comes down to diagnosing this deadly disease? https://www.ncbi.nlm.nih.gov/pubmed/31031033
