ooohh... I wouldn't. Aloe can sting on broken skin. Also while I don't know if it is unsafe to eat it does taste like ass... which is less of an issue if you are pumping, I suppose but anything on your nipple can get into the milk you pump, right? Do you have Lansinoh? It doesn't really have a taste and is safe to eat, so it doesn't interefere with nursing and it really works. Also it is soothing. Good luck with your difficult situation and with this decision.
