I can't remember where I saw this posted in the last couple days, but it is a great resource.

It notes that we should use Calcitonin Nasal Spray to prevent spread before invasive procedures.

I have not had time to really read it and understand all of it, but it also talks about vit. c and things to do to prevent spread with new injuries.

I saved a copy to my computer so I could put it on my iPad that I take to doctors offices with all my other info.
