My belly button is infected. Can I put white vinegar on?

Thank you for your question.  I am sorry to hear of your belly button issues.  Without photographs it is difficult offering definite advice but local wound care often entails ointment covered by a clean gauze, or lightly moistened gauzed placed within the wound which gets replaced 1-2x's per day until your body heals from the inside out.  If you can't see your surgeon seek a second opinion or another plastic surgeon's office in your area that would be willing to assist you.  

It is hard to give good advice without pictures or an i8n person examination.  It is best to followup with your operative surgeon to address any concerns you may have.  Usually local wound care and antibiotics will suffice.

You need to call the many boarded PSs in Orlando area. Say you are willing to pre pay for consultation. I would in my practice see you and render care. Fees usually start at $500..
