hi could be bv or a yeast infection or chlamydia these all have a burning effect if its the first two you could try sea salt as a cure. so what you do is have sea salt baths twice daily you put two handfuls of sea salt in a warm bath you need to let the water get inside your vagina for this to work you do this for a week by then it should be cured. for chlamydia you could try boric acid capsules just ask at your chemist for them. i think they come in 300mg you just slip them into your vagina twice daily. do hope this helps. good luck
does the sore always come back in the same place or can it occur inside the vagina too? . i have had genital herpes for years and my outbreaks are rare and mild. i take valcylovir (sp) i have itching and burning inside the vagina and some bumps inside. i'm wondering if this is an outbreak or vaginitis.
