Beth, do you suppose it might be worth trying Diflucan?  I just wonder
if she might have a subclinical yeast infection.
I think that until this is resolved, I would suggest that she not shave
under her arms, just in case the irritation from that is contributing to
the problem.
I expect that the doc has already gone over switching deoderants and so
on, just in case it's unrelated to the lactation.
Is it bilateral?
Can't remember, is it Epstien-Barr virus that can cause this?
Sorry, I'm just thinking out loud.
Good luck.
