20 week old Chocolate Orpington with leg injury. ..please help!

[SurfCityBumpkin]

Hi, all. My 20 week old Chocolate Orpington pullet has developed a significant limp. About 5 days ago I noticed her favoring a leg and resting a lot. Her middle "toe" curls under when she tries to walk on it. I checked her for a break but nothing obvious. What I do notice is significant swelling in her "knee". I'm sorry for the pathetic anatomy terms but I am new to chickens and not sure what the area is called. Appetite is normal.
What can I do to help her? So far, I have isolated her to let her rest and added Vi-Tal to her water. I would love some advice from someone more experienced than myself.
Thank you in advance

Ps she was vaccinated as a chick

Thank you. I have been scouring the web for clues and I noticed the aspirin in water also. I'm going to start that this morning. I am not sure if I can add it to the water with the vitamin supplement I am already giving? Any thoughts? She isn't improving and is now throwing her other leg out in front of her for balance which is making it impossible for her to take a step without falling forward.
