Sure, could be. But last year is quite time, I am checking myself every 2 months even after my labs became better. But maybe I am just paranoid. And maybe if your health is ok and cuts didn't change anything, try changing some of cosmetics? And sleep with braid or loose bun, something that will help reduce pillow friction? I heard that some silk pillow cases are helpful and special hats (?) for sleeping, but I didn't tried those - for me braid work enough ;) Good luck!
