Why does my mid thorasic part of my spin curve to the right, almost feeling as if its pushing into my muscle/ribs , & only part of my spine can't feel.

Scoliosis: A prominent set of ribs or a bump on the right side is typical for adolescent idiopathic scoliosis. Bend forward and touch your toes (adams test) and have someone check. Is there asymmetry? Then scoliosis likely. Most girls done with spine growth by 14 years (2 years after menses). If scoliosis possible, see an ortho spine doc for evaluation and followup. Surgery only for most severe curves.
