i have had this burning, tingling and numbness in my vulva and thigh area for 2 months and it comes and goes..i thought it was symptoms of herpes but when i went to go see my obgyn nurse practioner she stated the symptoms that i am having are not from herpes..and i have seen a couple other doctors for this and they have had said the same thing..but im still having the same problem..i have had no blisters or sores through this whole time..can any one tell what this could be.
