fingering prob, HELP!

H

my partners nails were a little long last night without me realizing until after when I felt irritation on my labia. Anyone else have this issue before? How long does the irritation take to go away? It’s literally just on the outter part not inside my vagina. It’s uncomfortable right now, but I don’t see any visible cuts/scratches. lmk if there’s anything I can do to heal or soothe that won’t cause me an infection!
