My dutch just got over her sore hocks. We trimmed her nails (even though they weren't that long), put some soft sunseed bedding in her cage, and treated the sores with a wound spray called Vetricyn. I would definitely recommend treating them with Vetricyn or something similar.
Depending on the severity, it may take awhile for them to go away and the hair to grow back. It took about a week and a half for Olivia's to go away completely, treating them with the spray a couple times a day.
