Small vulva fissures in folds that clear with neosporin. should i be concerned?

Yes, find out why: Recurring vulvar fissures need to be addressed as to why they keep making "guest" appearances, Neosporin notwithstanding. The first thought is to make sure that your vulva hygiene is appropriately done especially during periods. The use of mini pads for interminable hours is a prime culprit as well as harsh applied soaps that cause vulvar drying and cracking. See a GYN MD if this persists.
