When will the pain in my bakers cyst go away?

I'm 16 and I have dance recital in THREE WEEKS. May 13, 14. I recently ruptured a bakers cyst in my knee(either april 19 or april 20) and the fluid is in my knee. How long will it be for my body to absorb the fluid and the pain to go away so i can get back to dancing? PLEASE PLEASE PLEASE help, i'm begging.
