DiDi, I saw your post and it alarmed me. If you go to your primary care physician, you can get a medicine that will treat your thrush in the mouth. You should not wait on that. I have a lot of experience with yeast. I have had a yeast infection in my vagina for many years now. I have been going to gynecologists for a while now, none of the meds ever work for me. What I do not understand is why it wont go away. I am not diabetic, do not have hiv or a thyroid problem, and I really dont eat a lot of sugar. I always constantly worry that the yeast in my body will spread and that I will eventually get thrush. Do you know for a fact that the yeast in your mouth has spread to your lungs? If thats true....thats dangerous. I think that you definitely have a chance at treating your yeast. I on the other hand fall in that 5 % of women that have a problem getting rid of yeast infections
