Hi,
My daughter sprained her ankle and was diagnosed with RSD. In the process of treating that, she developed abdominal RSD from too many medications. She too participated in Dr. Sherry's program and like you did not find pain relief. We later discovered that hyperbaric oxygen treatments were able to stop her pain, and I would love to share her story with you and your parents if you all would like more information.
Take care and best wishes!
Jeanne
