No, that's (HBOT) one of the few treatments I haven't tried. Would you recmnd it? The reason I didn't when diagnosed was bec you had to do a lot of sessions in a short time when you start. As I worked full-time then, it was difficult to see how I would be able to complete this induction. Also my ear drum burst about 20yrs ago, but thankfully healed. But I didn't want to aggravate it.
I use the therapy centre to see the physio fairly often and to see a chiropractor every 2 months or so.
I first saw the OMS site in the summer after I was diagnosed so 2010 and read the book shortly afterwards. I know I sort of drifted into the program vit d3, flaxseed etc, but had definitely given up dairy by xmas 2010 (I didn't eat meat anyway). In Nov 2011 I got into meditation and started eating fish a lot more plus about 5000 fish oil capsules. I got a really positive MRI scan in summer 2012, showing no new lesions and no worsening of existing lesions compared with winter 2009. So I was really pleased with that!
