Can't "see" any reason.

My 14 mo old Pekin duck started limping maybe 4 days ago. This morning I noticed there is swelling where the ankle joint connects to the foot and is pretty warm to the touch. I did see a tiny scrape on the bottom of her foot but nothing else. What can I do to help her aside from cleaning it and wrapping it up?

These are pictures I just took of her, she is now shaking. Is it the pain or was the water in her pool too cold? It's the same cold it usually is but today she couldn't climb out so I had to help her get out :-(
