Getting throbbing pain in vagina, urinary urgency and burning. Tested for STD and UTI nobody seems to know what is causing it. I am 51 & permenopaus?

Could be:. Interstitial cystitis, an inflammatory condition of the bladder (but it usually presents earlier than age 51). Could also be an effect of loss of estrogen on the vaginal tissue - which can cause bladder problems and vaginal discomfort. Could also be vaginitis (yeast, bacterial vaginosis or other).
