i had vaser lipo done 2wks ago, and got a burn below my navel area, the md told me to apply silverdine cream 2x/day, now i have a wound with white stuff in the center and bright red wound surrounding. it does not hurt, smell, but it itches sometimes and a scanted drainage on the dressing. what is that white stuff and how much longer it will heal? i am a healthy 39 years old with 2 kids.
