I have had multiple chemical sensitivities, fibromyalgia and cfs for approximately 30 years. I have tried just about everything and many therapies have helped. I attribute these therapies to not being any worse than I am at this point. I am about to take hyperbaric oxygen thereapy, at least 10 units, because I understand that there is some evidence that the high level of oxygen that is infused into the cells could be responsible for killing the virus'es and bacteria since they cannot thrive in a highly oxygenated cell. I am curious about what others may have heard about this therapy as it relates to cfs and if anyone else has tried it.
