How soon can I play badminton after cheek lipo and rhinoplasty?

I had cheek lipo and rhinoplasty with ear cartilage used for the tip on May 17, 2016, 31 days ago. How soon can i go back to playing badminton? There's gonna be lots of jumping, bending over, and overhead movements involved. I am worried that excessive body and head movement would "stretch" my face and ruin my results. Risk of getting hit on the face is very minimal. are my concerns valid? Thanks in advance!
