Plasticat I've seen many of your posts on curezone. Have you tried zapping or using the Beck protocol? For serious systemic infections there is nothing that I can recommend more highly. Colloidal Silver will only work where it can reach and you have to take enough of it to have an impact. To me it sounds like you are fighting something parasitic which should respond to electrotherapy (zapping) if you do enough of it. Also a mind/body protocol such as EFT would be helpful in reducing emotional stress and the physical symptoms that go along with it. Sorry if it seems that we all jumped on you. It is rare to here Colloidal Silver not working for someone. With a longstanding systemic condition my guess is it would take a large amount of Colloidal Silver to work properly. Have a look at the Zapper Forum if you haven't done so yet. Zappers are inexpensive and work well for many infectious conditions.
