I did a research paper on necrotizing fasciitis and saw horrid pics of after effects of levo. Ironically two months later, my aunt developed severe abd pain that was disproportionate to the small discoloraton on her abd. Long story short, she had nf and was intubated and on levo in less than 12 hours. Multiple days and surgeries later, I was freaking out-she was still on levophed... Here I am half a continent away and not able to be with her, and I'm thinking the worst. She made it out with all her toes and fingers. She is disfigured from abd through genitals and down to her thighs, but she is going back to full time work this fall and is doing great. Without levo, she would probably not be here with us today!
