could be but also check out vulvadynia.... inflamation of the vulva with no known cause.... I have had this for years and the drs could not find anything wrong.... finally found out I am "wheat sensitive" and stay away from all wheat.... its better but that is not all of it. I have done 3 liver cleases with stones every time.... 30-100 each time. I am feeling better still but have a way to go. good luck finding an answer
