c1 fracture recovery, I'm 16, a lifeguard...when?

Hello my name is Courtney and I am a 16 year old girl. I was in a car accident and I had a stable fracture of my c1 and no spinal damage. I was put into an Aspen neck brace for 6-12 weeks. I am almost at my third week and i have a few questions. I stopped taking all pain medication after 1 1/2 weeks because i have no pain. I am a very active person and competitive swimmer and waterpolo player. I want to know how long it would be until I am allowed to get into the water and do some light leg work? Also, I am a lifeguard and want to start work again and for safety reasons I would be put on dispatch which is very light work. I would have no chance of having to save someone and I would only tell people when they were allowed to go down the slide. I would be sitting in a chair and under an umbrella. When would I be able to do these things? I want to start getting back into a routine.
