You may not have candida. Or, you may have candida and one, or more, additional problems. Everybody wants to buy in on the reassuring fantasy of an onmiponent and infallible medical establishment. If everybody knew how exactly limited modern medicine is, there would be a lot more people taking early retirement. Or, maybe not start a work life at all.
It is interesting, die-off gave me a killer case of sinusitis. Of course, Antibiotics would have done no good for me, my sinusitis and sinus headaches were a response to the toxic chemicals released by the candida when they die off. Was a culture taken that confirmed bacterial sinusitis? Is there any possiblity that your sinusitis was also a sympton of die-off? How long did your MD have you on Nystatin?
