Recently had a test by my OB/GYN do not have a uninary tract infection.  About the same time as this I started having a problem with my Metformin and had to go off of it.  My diabetes is really bad right now so I have a lot of thirst and urinate A LOT....so my external vaginal area is inflamed and burns when urinating and after, it also itches.  I have used vaginal wipes, vagisil, Estrace and have had no relief for over two weeks, does anyone know what could have caused this?  The Diabetes or the test?
