My 14 year old dtr has received a diagnosis of compressed long thoracic nerve. It began in the fall when she (currently 5'4" and 100 pounds) played the tuba in her high school marching band. She also played softball on non band days. She complained of shoulder pain on and off but by Oct. She was in constant pain and said her arm felt weak. She saw an orthopedic who called it "unstable shoulder" and we were off to PT. It seemed to help with movement initially but never the pain. Then about 3 weeks in to PT it got worse. F/u with orthopedic was disappointing when he didn't even have her take off sweatshirt to look at winging scapula. I found a pediatric ortho who ordered MRI of shoulder (normal) and referred to neurologist which lead to an abnormal EMG and dx of LTN compression injury. Neuro called on phone and said poor prognosis for recovery and told me to f/u with pedi ortho and then see when I would go back to her. Neurologist gave no treatment ideas at all except do nothing for 12-18 months and see. I am looking for second opinion but wonder if should be surgeon. ???microvascular??? I hear of nerve surgery for severed nerves. Need ideas for next step please
