Does vulvodynia cause symptoms similar to yeast infections such as itching at the opening of vagina? no bumps. just a little bit of redness. no stds?

Vulvodynia may be possible, but generally is defined not by itching but by pain, often primarily during sex; and without visible inflammation (redness). A yeast infection may be more likely. Discuss with your doctor, or maybe try an over-the-counter vaginal yeast treatment. Good luck.

Though candidiasis can cause myriad of symptoms, I will suggest you visiting your Ob/Gyn for proper diagnosis and treatment. Vulvodynia is not the usual presentation of candida. Hope it helps.
