I scrubbed it with betadine and put some nitrofurisone on it. Didn't bother her. Tomorrow I'm gonna put some fungal cream on it too. I was just wondering if she might have gone up against tree bark or a shrub. She's got two gashes so I know she's been fighting. If it was a dermatitis I would thing her coat would be bad in other places but she looks good.
Well, I just thought of something, the times I've seen rain rot it has thick crusty scabs on it. Sounds like she could be rubbing it on something.

My oldest horse, Tennessee, used to get something similar on the sides of his thighs back when he was young. They were hard bumps, with a scab that you could pick off like rainrot, but were in an unusual place for rainrot. They left pink areas like in your picture when you picked them off though. She may have been rubbing them on a tree or something and that may be what caused the cuts. I'm just guessing here, but your course of treatment sounds like it ought to take care of it, no matter what it is.
