Anyone tried collidal silver in nostrils for sores?

I was wondering if anyone has tried this as some of the silver sites mentioned this. I have a terrible irritation in my right nostril and am having a problem with Bactroban and Bacitracin.

Since there are so many out there and who knows what one can be trusted I would appreciate it (if it is allowed) if anyone has tried it could you please post the name of the reputable one you used and how well it worked. Supposedly it kills bacteria, viruses and fungus and heals. I know CVS has their own brand of microbial silver gel for wounds that says for external use only but then so does Bactroban and Bacitracin.

Any info would be helpful. Maybe we can wipe out nasal sores, staph, sinus congestion, etc.

Thank you.
