Hello friends...its been a while.
I have been reading this post and trying to hold back but as some of you may have figured...I have to jump in. I am pleased to see this topic come up year after year! I am very disappointed that HBOT for RSD/CRPS is not used more commonly. mryan, thanks for your post!
I 'll try to keep this short because most of you already know this, but for the sake of this thread and Krank I feel I must reply.
I have full body RSD twenty years this past July. My first trip for HBOT was to Canada. I did ALL forty dives (highly recommended amount) at 1.5ata. I stayed at a facility and the expense was much less than in the USA . I didn't have insurance. There were children with CP, stroke victims, MS, and RSD patients. I benefited greatly from these 40 dives. BUT, when I got home I continued to see improvement for weeks after treatment. I had very good results for about eight months, and then needed to return for more HBOT at about the 1 year mark.
After the results of the first forty dives, I decided that I would learn all that I can about HBOT, Oxygen and Open water diving. During this process, I went to Texas and did 40 dives at 2.4ata. Again, the results were great. I continued my scuba diving lessons and earned my Nitrox (enriched air ..more oxygen in air mixture) and became a rescue diver.
One year later, I again, required more HBO treatment and went to Texas for 40 more dives at 2.4ata. It was at this point I decided to purchase a HBO chamber. There are also others here that have HBO chambers and have great results with them as well.
Recently, while working with a Doctor to treat his parent with Alzheimers the results I saw again were amazing!
I totally agree with the previous post about the benefits of HBO treatment! I am in NO way advocating a in home chamber for anyone. There are so many precautions, requirements and certification needed to operate the chamber safely. But here are some of the benefits of HBOT:

Research has shown that at 1.5 ATA, many of the regulatory hormones, neurotransmitters, and enzyme systems operate in a balanced, optimized state.
HBOT also produces several long term health benefits, including enhanced growth of new blood vessels (angiogenesis), optimization of the immune system's ability to remove toxins and destroy bacteria, increase the activity of fibroblasts (the cells responsible for tissue repair) and enhanced metabolic activity in previously inactive brain cells.

Most people have only heard of using a hyperbaric chamber for the "bends," another name for sickness brought on by an air embolism. But many other conditions such as stroke, cerebral palsy, head injuries and chronic fatigue have all benefited by HBOT. Macular degeneration has also been alleviated, as have any disease associated with oxygen deprivation. Healing of some areas of the body cannot take place without appropriate oxygen levels in the tissue. Illnesses or injuries often linger at the cellular or tissue level, thereby taking longer to heal. In many cases, such as with circulatory issues or nonhealing wounds, adequate oxygen levels cannot reach the damaged area in order to heal naturally. Hyperbaric oxygen therapy provides this extra oxygen naturally and with minimal side effects.
Stem Cell Increases
HBOT assists your own stem cells to regenerate damaged tissues, which is crucial to accelerated healing. These progenitor stem cells (not to be confused with embryonic stem cells) are crucial to the repair of injured tissues and organs. In response to injury, stem cells move out of bone marrow to the injured sites, where they differentiate into specialized cells that are important to the healing process. Stem cells from bone marrow are capable of providing specialized functions in many different organs and tissues throughout the body. This movement, or mobilization, of stem cells can be triggered by a variety of stimuli---including pharmaceutical agents and hyperbaric oxygen therapy. Hyperbaric oxygen treatments increase by eightfold the number of circulating stem cells throughout the body.

The protocol of 40 dives minimum seems to be very reasonable and again I saw improvement up to six weeks after the treatment. I found a reduction in swelling, less inflammation, drecreased pain, more mobilty, increased circulation (no more mottled skin) and a sharper sense of awareness (less RSD brain). Oh, better sleep, and more energy, also. I still do series of 40 dives and maintenance dives.
Although I have heard some say that they were cured after 40 dives, this was NOT true for me, personally. I continue to treat with HBOT on a conservative schedule..as I personally am not sure of the consequensces long term use of HBOT.
All the best to you Krank on your endeavor to find an HBO facility. If you have any questions, you can pm me. Blessings...Di
