I had hyperbaric oxygen treatments for a severe infection and was able to avoid an amputation because of it. It works.
so were you treated in a REAL hyperbaric oxygen chamber that dives to 45 feet and was pressurized with pure oxygen, or was it one of the balloon ones that go to 14 feet and are pressurized with ordinary air and you breath oxygen through a mask in the chamber ... there’s a YUGE difference (and cost) ...
