Noticed puss coming from my belly button 7 weeks post op. Should I worry? Could I have an infection inside? (photo)

At 7 weeks after a tummy tuck, it's unusual to develop a serious infection.If you have pus coming out of your incision, you likely have a small localized infection around a suture. Definitely make an appointment with your plastic surgeon to be evaluated. Thanks for sharing. 

Thanks for the question.  What you are describing is a stitch abscess.  This is just a small area of infection around a retained stitch that was placed at the time of your tummy tuck.  Yes, that was likely a small amount of pus.  No, this is most likely not a big deal at all.  If the stitch came out completely, then the area will close up and heal.  If you still notice the stitch or other stitches, call your surgeon and go in so he or she can take a look and remove any that haven't dissolved.  In the meantime, continue cleansing the area with antibacterial soap and water.  If you want, you can put a small amount of neopsorin on the area and cover it with a bandaid.  Best wishes!
