Help with my Scaphoid Injury?

I had a bone graft scaphoid surgery with screw fixation does in January 2011. It took me about 60 days to recover but the bone healed completely. However there is still a little bit of pain when I move my wrist in certain ways such as moving it backward or when attempting a push up. The doctor told me to do physiotherapy. My question is, is there anything I can do at home that can help me subside the pain in my wrist?
