Hey Brandi,
I occasionally get scratches and stuff that I don't remember having happened. I am fairly disconnected from my body so when it comes to scratches I know that it is because I was concentrating on something else and didn't realize that that I had scratched an itch deeper then needed just because I didn't feel it at all at the time. I don't think it is anything to worry about especially since you feel good. I believe your husband is right, it is just a matter of becoming more aware of your body.
Take care,
Carrie
