i had vaser lipo done 2wks ago, but i got a burn under my navel area. md told me to put silverdines cream 2x/day which i did. however, i noticed white cheese looking thing inside my wound around 1wk post lipo. there is no pain, no foul smell, little drainage noted on the dressing, bright red surrounding on the wound. what is that white thing? how long will it take to heal? thanks for your answers.
