A woman nursing a 13 mo old has a section (11 to 1) of one areola that
shrivels/puckers/becomes noticeably raised (as a piece of fabric would
become raised when it's gathered) at random times and stays that way for
hours.  It doesn't seem to be related to nursing or cold, tho it is most
likely to relax in the shower.  There is sometimes slight discomfort there
at latch-on, which dissipates quickly.  She's taking Loestrin.  Her bone
density is considered low for a woman her age (mid 30s), no other health
issues.  This has been going on for about 2 mo, and she doesn't know
whether to be curious or concerned.

Any guesses???

(By the way, I wrote about this woman a few months ago, when her bone
density was even lower.  Sure enough, it has rebounded to pre-pregnancy
levels, despite continued bfing 1-3x/day.)
