I hope I have picked the right forum for this. I want to ask if anyone has tried Hyperbaric Oxygen Treatment? I found this paper on Hyperbaric Oxygen for Fibromyalgia alone which was strangely ignored back when it was published in 2004: http://www.ncbi.nlm.nih.gov/pubmed/15174219 It found that Hyperbaric Oxygen Treatment helped Fibro. However the numbers are small. I have a physically healthy friend who visits a HBOT treatment center here: http://www.assafh.org/sites/en/Pages/27YearsAfter.aspx She has ADD (Attention Deficit Disorder) She is in a study where they are trying to see if HBOT helps ADD. She told me that everyone sleeps better with the treatment and that SPECT show more blood flow in the brain. Reduced cerebral blood flow is known to happen in M.E/CFIDS Is there anyone here who has tried this? I would be so grateful for any information, however small.
