Anyone interested in this treatment should really do some extensive internet research. It didn't take much digging for me to find some questionable posting at other sites that look like hype from one patient that might have a personal interest in the company. Buyer Beware and all that...

If you have out of pocket funds and haven't tried HBOT, it is worth a shot. I've never heard of it causing spread, and it reduced my swelling and pain.

Stacking non-invasive treatments is also something to consider.

If you can find an infrared sauna, you want want to try it out as well. If you can tolerate massage, not too light--not too deep, it has helped me. Warm water pt.

I have been able to fend off escalating RSD symptoms that SURE seemed like spread, by aggressively utilizing meds and the aforementioned, including an ankle problem that had been getting slowly worse over the span of a few years.

Have you tried Hooshmand's 4 F's diet?

Or meditation? The audio book by Andrew Weil, "Breathing:The Master Key to Self Healing" is a good place to start IMO.

Yoga or Tai Chi, too.

If I'm sounding like a broken record y'all, please excuse me!
