I will be 45 shortly. For the past several years, I sometimes get this
burning sensation on and off in vagina not on the outside. Sometimes intense, no itching; nor, is there any unhealthy discharge, no odor. It mostly happens a few days before my period begins. At the very onset of my period begining to flow, it really burns. Once the flow is going, it stops burning and I'm fine again until the following month and the process sometimes resumes.
