Exercises you can do after nose surgery...

It's been 2 weeks... the swelling has almost gone... the tip of my nose is still red... I don't know when it will go away... I've been stuck at home eating and sleeping since I had the nose surgery... so I've gained a lot of weight... 1. Exercises you can do Is there anything missing?? Sometimes I do walking exercise while watching TV at home. 2. When can I start sweating and running? When can I start swimming?? Because I like somewhat extreme exercises...^^;; I like to exercise, but since I haven't moved much for two weeks, I'm just gaining weight and I'm feeling frustrated..ㅠㅠ
