We heard back from a gynecologist associated with the website. Here is his response to your question:
"When a vaginal infection is as resistant as yours a visit to a
gynecologist who specializes in infectious diseases is most
First consideration will be given to diagnosing the specific organism causing your problem or if there is some other cause such as chemical contacts or medications. For example, soaps can be a factor in yeast recurrence, especially soaps that are anti-bacterial.
Yeast organisms have become more resistant to medication and a specialist will be aware of new drugs for overcoming resistance.
You are at an age when you may have a relative deficiency in estrogen especially since you see the problem aggravated by having your period.
Estrogen affects the pH of the vagina, vaginal blood flow, vaginal thickness and maintenance of normal bacteria. With estrogen deficiency, change in pH, blood flow, vaginal cells of bacteria can predispose to the growth of yeast. Estrogen deficiency is easy to overcome with vaginal estrogen tablets and that may make a difference in the effectiveness of the anti-fungal drugs.
By now diabetes has probably been ruled out. If not, then you should be checked to see if you are diabetic or pre-diabetic. When that is the situation, yeast are particularly difficult to treat but at least you'll know what you're dealing with and once that is corrected the yeast can be more readily treated.
Finally, it's common for yeast organisms to "hide" beneath tissues-behind the labia at the vaginal opening or under the skin covering your clitoris. It's important that medication applied to the tissue gets to all the little areas where yeast can reside.
Ask your gyn if he or she knows a specialist in infectious diseases who could see you."
We hope this information helps. Please let us know what you find out.
