I think you just need to step back, take a deep breath and let her rest for a few days. Birds can get injuries just like you do..... Sprains, strains, tears, etc etc...
If she is only acting ouchy on that leg....and not sick, I'll or in any real pain..... If she's not pasted on the back end, hasn't stopped eating or drinking, color mostly looks good..... Then just watch her. Sometimes doing too much can cause problems rather than help. Watery poo can mean she is drinking more...could mean all the extra stuff she is now eating is changing her poo.. Bright bright green ....can mean infection.... If you don't want to wait then you can take a fecal to the vet and have them see if anything is amiss internally...then go from there.
