Sore between front legs

[jenn]

My boy is still living out at the moment, although he has had a light clip. He is increasingly fidgetty when I brush between his front legs, even snapping (so out of character). I can't see anything but can feel some "scurf" spots which I've brushed off and mud. I try and wash the girth area every time we ride, and that is why he is lightly clipped as he does sweat a lot there. he has very hairy legs as well and dislikes the tops inside being brushed. Back legs fine.
