Got a new tattoo. it has infection. (cellulitis i think)i saw a doctor today and i have antibiotics. how do i take care of my it? wash? soap?

Keep it clean: Wash with soap and water unless your water is well water. If so use saline to wash it. You also may also need to be tested for blood diseases.

Neosporin: I would just put neosporin or some triple antibiotic ointment on it for now. That should keep it moist , treat infection and allow it to heal.

Local hygiene: Wash with soap n water. Dry. Apply antibiotic ointment and cover the area with some type of a dressing ie telfa pad bandaid etc.
