You must clean the area well with soap and water and dry gently. You should then apply an antibacterial ointment and apply a covering such as a band aid. Do this daily and if it continues to ooze see your doctor.
A wound oozes as one way of cleaning and preventing infection. You can help this effort by using an over-the-counter topical antibiotic ointment, such as Neosporin or Polysporin, and covering it with a Band-Aid.
