I thought I might have a yeast infection. I am 54 years old, married same partner for 27 years. I am still having monthly periods. I have symptoms similar to a yeast infection. Friday evening I took a Monistat 1 suppository and used some of the cream on the outside of my genitals. Since Thursday I have had pain on the outside of my genitals and pain in my lower back. A couple of times, I have woken up covered with sweat. The pain is not getting better. Do you have any ideas?
