I picked up my 8 month old guinea pig today to trim her claws (which I've unfortunately been neglecting, however I don't think that has to do with this problem, as they're not terribly overgrown). As I was clipping the claws on her front foot, she was struggling as usual, but I flipped over her foot in the process of trying to get her to hold still (blanket and soft music helps, but doesn't solve the problem completely). I noticed some greenish patches on the pad of her front-left foot. Same on the front-right, but not as big. It's not on her back feet. I Google Imaged Bumblefoot, as I've heard a little bit about it and know it can be really painful for a guinea pig. It doesn't quite look the same, though. I picked at the green spots a bit thinking it was just dirt, but she didn't seem to like that, and it didn't come off after gentle picking, so I left it alone and put her back in her cage to make this post. What is it? What can I do about it?
