I have bad vaginal itching, strong urge to urinate and burning feeling while urination. This problem comes and goes without any reason. It can torture me for several hours ,disappear for days and then come for a week, or it just stays for weeks -- comming and going (several hours, nights, mornings)... It starts just with vaginal itch, then the itch gets worse, then i have to urinate more than usual, then i get pains during urination. Yesterday it came at around 1PM and i had it all day. I could not fall asleep untill 12:30 AM because of it.
It makes me feel tired. Any move i make brings me extreme discomfort.
The discharge can be different: it starts with white and when i feel especially bad it gets yellowy.
I have herpes, but several tests showed that when the vaginal burn and frequint urination happens.
now I am hoping for any kind of advise as it is goming and going for almost 3 years. 7 gynecologist i've been through could not find the couse .

Thank you
Anna.
