Kidney dislocation in right shoulder.

When I was born as a baby the nurse carried me from my right hand which caused me a Kidney dislocation in my right shoulder.. then I couldn't move my hand and use it.. it was like a wood arm on my body... my parents asked many doctors but every one of them was saying the same thing (that my right hand will never grow up as my body do, and I will never be able to use it)...... No one could fix my problem but... only one doctor could make me move my hand in front of my parents' surprised eyes... he told my father to regularly rub my hand with olives oil and black seed oil..... now I am a good player in my basketball university team. I already was a player in a volleyball team. my hand grow up and I can use it with limited moves SO, I am here to know how I can break the limits of my hand moves and to take some advises of certain exercises which I can do; so that, I will be able to move my hand more what the limited moves I mean: I can't straight my elbow and my shoulder well. please help
