I began to feel an ear ache that became increasingly painful to the point that I couldn't ignore it. I had colloidal silver on hand (10ppm) and put a couple drops in the affected ear. I felt a slight bubbling but within minutes lying on my side to allow the silver to penetrate, I felt the pain subside. I then began to resume my activities. I felt it return once more, I repeated the same procedure and soon enough pain subsided but this time never returned. I believe the colloidal silver quickly conquered an ear infection.
