Keep us updated on her! She's a lovely SS (I have a couple myself and absolutely LOVE the breed) One of mine is in my Hen Hospital right now due to a suspected broken toe. Her poop was really liquid and sparse the first couple of days, but she's eating, drinking and pooping normally now. And squawking at me to let her out with her sisters. I'd back off the aspirin and perhaps give her legs a nice soak in an epsom salt bath. Get her in a sling if you can and give her some time. I'm amazed at how well animals can heal-especially chickens! (Note: my Sophie seems much more content when I have music playing for her. In her case, she loves reggae. Perhaps your gal would be more relaxed with some music-to-heal-by?)
