I am a 56 year old woman with generalized dystonia. I have bilateral deep brain stimulators. Recently I began horseback riding lessons, a sport which I greatly enjoy, and will help build core muscle strength. I have difficulties with balance, and want to develop my core muscles. I always ride with a helmet. A few weeks ago, I was thrown by my horse and have fractured ribs (ribs 2,3 and 4) and a fracture of my shoulder. My ribs resulted in a pneumothorax of my right lung, which was treated with a chest tube. My doctors are of differing opinions about the advisability of my continuing to ride. Want to weigh in?
