I've researched about HBOT too, but being on the good ole NHS, they don't offer it, and the cost is way out of my price league. I'd love to try it, the science is sound, there have been some good results, and plenty of folk seem to get something out of it...
DJhasty, it would be brilliant if you did a diary about your HBOT, I'll be fascinated to see how it goes for you - and I'll keep my fingers crossed that you achieve some pain reduction. That would be worth any amount of time and hassle
Good luck.
Bram.
