I have had a small green discharge for the last 2 months. I have had 2 courses of Metrinidizole and one 6 day course of canesten vaginal cream. I have had a swab done at a gynea clinic which has come up perfectly normal and no problems. Is it possible I have a bladder problem, rather than a uterus problem? I do notice a very mild dull ache from time to time in my bladder, but have no pain or frequency passing urine. I am 61 years old. Is this something I have to learn to live with in old age? Or can I have some sort of treatment.
