Can you have a yeast infection without much discharge (instead - red, irritated, burning skin on the vulva, little itchiness)?

Typical symptoms!: Contrary to what you seem to think (or what you have been told), increased discharge is not one of the main symptoms of yeast. Your own symptoms are exactly what I teach medical students to look for and patients to be aware of. See a doctor to confirm the diagnosis. Or you can try an over the counter yeast medication -- then see the doc if symptoms don't clear up in a few days. Good luck!

It's best to see a Gynecologist for a thorough examination and recommendation for treatment, If you have a yeast infection use Monistat 7 for all 7 days.
