hello, i was born with this condition kyphoscoliosis I had surgery when i was 9 years old, there was an improvement.I am now 21 years old.my left leg is weaker than my right one, in fact it s very weak, and sometimes i keep getting pains on my left chest, my questions are; is it possible that i can ever have a straight spinal cord, even if i have another sugery? is it hereditary? and lastly can i perform exercises such as press ups etc to keep fit, if not what exercises can i perform? Thank you.

Summarized question: Is kyphoscoliosis hereditary and can surgery correct it?
