I have tried the HB but not the ozone. I have heard great things about
ozone treatment. As far as the HB I did 20 treatments and did not really notice much of anything changing. I had real trouble with the pressure and my ears, so if you have any trouble with flying etc. you will not do well with HB. Doc wanted me to have tubes put in my ears (like they do when kids have infections) and I said no thanks to that. I have met people that have felt better with HB but when they stopped doing the treatments, symptoms returned. Its also very pricey, I paid $150. an hour and they recommend that you do at least 40. I would try the ozone. D
