I hadn't had intercourse in a year. Never had any regular history of yeast infections. In the past couple-3 of months, I have had several- at least I think anyway. My symptoms are the same- discharge, irritation/itching and a foul/sour odor. Even I notice myself smelling differently. Do I have an internal infection or is my partner carrying something and passing on to me? Plus my insurance just ran out and am searching for a new health care. Not good timing for me. Any suggestions?
