Thank you for offering to share your experience with the HBOT treatment. I have been researching the HBOT treatment the last couple of months as all other treatments have failed (ketamine infusions, nerve blocks, and numerous other misc treatments) so I'm really left on my own to figure out the next step. During one of my hospital stays one of the Dr.'s performed an oxygen test and both of my legs (the crps is isolated to both of my legs) had less than 70% oxygen saturation which is really low. I really think oxygen therapy will help but insurance doesn't cover it and I'm not working so I can't afford to spend anymore money on a hunch... Let me know how it works and I wish you nothing but success.
