Hi! Im 14 years old and I have been having a lot of back pain mostly in my lower back and then shooting up my spine, so I went to my doctor and had x-rays taken and when they came back I had slight scoliosis. I have to go to physical therapy and my therapist is telling me that another thing that is hurting my back is that I have rounded shoulder blades. When I do some exercises like laying on my stomache and putting my arms straight forward and lifting them, I can barely lift them at all. She tells me that I am very weak. so…my question is do you think this is that big of a deal like doing the exercises or just do you think it is sort of serious????
