Hi Colleen. Yes I had already read most of them. Interesting that there isn't more commentary on Stem Cell, platlet rich plasma or infrared than there is. Understandably the therapies are still pretty much in their infancy and to some degree experimental but treatments also include nutrition and nitrous oxide production. My wife is in stage III and needs to do something. The traditional therapies did not work for her. Taking pills isn't working. I will continue to monitor the site. Hopefully there will be more input at some point by people who have had these newly developed treatment plans.
