I could have written the same post myself last year. It was agony and completely destroyed my sex life at the time. I had bacterial vaginosis which is very hard to treat because it usually reoccurs. I'm on my iPod so can't reply in full til I fire up the main computer. If you google it you will find lots of info on it. You should definitely get a swab done and start on a peserie antibiotics. Thrush cream only gives a tempory relief if it is vaginosis / vaginitis.
