Hi, I am a 76yo wh female, I have recurrent pubic irritation, no discharge. It seems to be relieved by drinking 2 glasses of buttermilk dly. My thyroid tests are wnl, checked yrly, my last fasting blood sugar was 101. I am approximately 25 lbs. overweight, I take Lisinopril/hctz 10/12.5 dly and mvi, gingko, asa81mg. I am very active and have no other known health problems. I also use zinc oxide ointment as needed. I believe it is yeast but it seems excessively stubborn. Any suggestions?
