Is this a suture abscess or a possible infection? (Photo)

Thank you for sharing your photograph and question.  Normally, an infection would show more redness and swelling.  The picture you sent us is a classic sample of what is known as a stitch abscess.A stitch abscess is when the body tries to dissolve a stitch.  It sends in white blood cells whose enzymes try to dissolve the suture but for unknown reasons, fails to do so.  This leads to a swollen pimple like area, which when opened, gives off pus which has all the signs of a bacterial infection but no bacteria.  Also, at the base of your picture, one can see a suture.If you were my patient, I would remove the suture which then allows the body to heal faster.  I disagree with using over the counter antibiotics because they often lead to an allergic reaction which turns red and makes you think you are infected, then you use more antibiotics which then turns red, etc. etc.  I like topical antibiotics like Silversulfadiazine cream or a generic Bactroban.  All the above mumbo jumbo means I don't think you are infected.

Thank you for your question and photo.  Sorry to hear about your healing problems.  I agree with your surgeon,  looks like an are of slow healing due to a suture abscess.  Generally these will heal on their own with local wound care.  It may take several weeks for it to heal, so be patient and follow your surgeon's instructions.  Of course, if things appear to be worsening, give the office a call and they may see you sooner.  Good luck.  

I agree with your plastic surgeon.  Continue to care for this as he or she instructed, and it should get better in short time.Best of luck!
