I had diep flap reconstruction about 8 weeks ago. I had an infection when leaving the hospital that caused an open wound. I fought the infection for about 6 weeks. Now that the infection is gone I have a strong odor and yellow, oily, discharge. I'm going to my plastic surgeon in about 4 weeks. Should I be worried or call him? What is this? Also there seems to be a pocket or hole up under the top of the open wound. Seems there is an absence of tissue.
