Suggest Treatment For Production Of Milk After Abortion

I had an abortion 8 years ago. The medication I was given made me produce massive amounts of milk. From that I got a lump in my armpit. The doctor told me that is was milk and that my hormones are "out of whack". My periods have never been the same and now I still produce milk around my period. My armpit alway swelled and became sensitive around my period but the past few months it has bothered me more than usual. Can you tell me what might be going on and should I see an endocrinologist?
