Fused vertebrae? Is there anything I can do?

Went docs last year because I had a "hump" back as my dad said. He refered me to see a specialist and she said it was a lack of calcium when I had a major growth spurt. She said physio will work so I went. Now my back isn't any better. It not painful only when I lie down but it's more of a confidence thing. Is there anything eles like surgery Or is it one of them things? ThAnks
