Suggest Treatment For Scoliosis

I just had a baby a month ago and was recently diagnosed with scoliosis. It was caused from muscle spasms in my back from being pregnant. While I was pregnant,I couldn't gain weight and got really skinny. I was below my prepregnancy weight a week after giving birth. I am back to normal now, except I can't seem to gain weight in my thighs. Does this have anything to do with my scoliosis? Also,since my scoliosis was caused from pregnancy, can it be fixed?
