Kathy,
10 years ago I learned a lot about breast incisions and leaking milk in an
unusual way.  At that time I was functioning as the Area Professional Liaison
for LLL of Va.  Late one night after my husband and I were both asleep I
received a phone call similar to your case.  A woman had an I & D of a breast
abscess 2 to 3 weeks earlier and it was still draining through a surgical
drain.  The doctor refused to remove the drain until the drainage stopped.
 What to do?  She was soaking wet all the time, housebound and constantly
changing bandages.  Suddenly, my husband who I had assumed was sound asleep
announced "Tell the doctor to sew the *blankity*  thing up.  Then the milk
will go where it is supposed to go!  As long as he leaves it open  the milk
will follow the path of least resistance and come out of the wound!"  To
clarify this, my husband is a veterinarian and operates on lactating animals
frequently.  It is often impossible for him to avoid cutting mammary tissue,
but a little milk in the wound is never a problem.  I think this is another
example of people (doctors in this case) mixing up milk which is normally
sterile, with some other type of excretion from the body, in this case a
 purulent drainage (pus and infection).  There is a huge difference between a
wound draining pus, or breastmilk.   What I recommended was a consult with a
doctor who was more familiar with surgery on the"lactating" breast.
Unfortunately I never did find out the outcome of that late night call.
