Skin Problem Again

Abby now has a new skin problem in the same area on the other side of her head in the area where the fur is really thin and you can see the skin.  It is similar to the cut she had.  I noticed it yesterday.  The other problem cleared up on it's own and I'm hoping this one will too.  She still has the feline acne on her chin but I am watching it closely and trying to brush her chin.  Soon I will start attempting to clean her chin with a wash clothe and water if she'll let me.
