I am a 21 yr old female. For many yrs now I have suffered from a coming and going pain in my vagina. I sometimes get this white odorless discharge. When I urinate it burns at times, but the pain comes and goes. I have been to a gyn many times and always come out negative for anything. I have not had any sexual intercourse of any kind for at least a year because it is painful. I am not on the pill. Can any one please help?
