I presume that you have finished the course of the antibiotics about a week ago.
If that is the case, make an appointment with your doctor. Although the abscess
is draining the "plug" needs to be removed. If the "plug" of the abscess
has not come out, the abscess
will continue to fester.
As the abscess
is oozing slowly means that you have an open wound and because of that you are unable to apply a magnesium sulphate drawing ointment.
