That doc and hyperbaric site is in Florida. The hyperbaric oxygenation is 'supposed' to help the nerves regenerate so they will stop misfiring. Last I heard, it still wasn't FDA approved for RSD, so insurance companies won't cover it......maybe that's why you haven't been offered it. Like the ketamine coma.....sounds promising but not available to all of us yet.
Maybe with these fello RSD'ers trying it the regs have changed and it has been approved and I just haven't heard it yet
