Nineteen is really young to be saddled with kind of pain. I also fell due to a skiing accident. L1 compression fracture that resolved itself. The only things that helped me include a neurologist who spent a long time probing my pain. She came up with a cocktail of meds that were really helpful. A year later I had a spinal cord stimulator implanted. Along with the meds it helped me get my life back. At this point it might be helpful to see a neurologist. They are often able to diagnose nerve-relate issues. Make sure you can find one who is willing to spend the time necessary to fully analyze your issues. I wish you well.
