In my opinion no one should even think about intravenous colloidal silver unless it is done by a qualified professional.
Do you happen to live anywhere near Dallas?
It may be that you need a better brand of colloidal silver, unless you are using Utopia Silver or Mesosilver.
And you might also consider some other good natural pathogen destroyers, such as:
• Olive leaf extract
• Oil of wild mountain oregano
• Grapefruit seed extract
The Silver Puppy makes a very good home product, you just have to take more of it than the really potent commercial ones.
Alas, I do not know of any professionals who administer intravenous colloidal silver. If you lived near Dallas or were able to travel there I might be able to help. I wish I were at liberty to say more. I will see if I can find information to pass along.
All the best,
