Interesting!  30 + years ago when I was having so much trouble with blocked
ducts, breast infections and out right mastitis, I was also very "yeasty",
as were 2  babies I nursed during this time and had oversupply problems.
Antibiotics given sometimes, nystatin for babies.  Which came first, the
chicken (yeast) or the egg (antibiotics)? I seemed to be in a very vicious
circle, that's for sure.  Wonder if there is any info on concurrent yeast
infections and PDs, BIs and mast.?  Would be a very interesting item to add
to any future research.  Sincerely, Pat in SNJ
P.S. I did find bra type and lying down to  nurse had significant impact on
plugs.
