I don't think it will be anything to worry about either, maybe she is just a little sore now. The toes don't look swollen to me (I honestly can't make out a difference between the two feet so I am not even sure which foot is the one she hurt, oops)
In the case that it's just sore, she should start using her foot more again in the next couple of days. If her foot does seem to become swollen/thicker compared to the other, if she still refuses to stand on it after a couple of days, stops eating or if there are strange changes in her behaviour, I recommend consulting your vet and having them check her out.
In the mean time, I'm sure she won't mind a little extra pampering and TLC
