Do these lipoma removal stitches look un-healed and/or infected? (photo)

Thank you for sharing your question and I am sorry to hear of your recovery issues.  It appears that you still have some swelling around your incision site as well as redness that is either related to the antibiotic ointment or an adhesive covering you have been applying.  Depending on whether your surgeon placed stitches beneath your skin as well as the black ones seen, it may be okay to remove these until your body heals the skin.  Typically I would wait 10 days or so before removing stitches in the lower leg.  Your surgeon will be your best source of information as they know the details of your procedure.
