Hi, I am currently 8 weeks post op from a full tummy tuck with muscle repair. I have been healing wonderfully. Yesterday a small pimple like bump that was white in color formed on my scar. After about a day it just popped on its own and a small amount of white puss I guess came out. It looks superficial. I didn't see a stitch or anything with it to make me think it was a popping stitch. It looks ok now just a little red. What was this and should I be concerned or go see my doctor?
