Thanks so much for all the replies and advice! I really appreciate it! If it is an abcess what can I do for that? Only thing I'm wondering is why she isn't flinching when I press hard on her legs and hooves? Is that normal with an abcess? I won't give her any bute now, just keep watching her.
I have a corral I can put her in, so maybe that would be better than stalling her. I sure know she would think so!!
If it is an abscess, soaking her foot in epsom salts at least once daily will help draw out infection - there is lots of information on the forums regarding abscesses... the good thing is that they're a very minor thing to have wrong.
