I have been experiencing a burning sensation in my vagina for a year. It feels as though the vagina is opening up or becoming distended, and I have a white discharge. I have consulted six different gynecologists, yet none of them seem to understand what is wrong. Although I do not experience any significant discomfort, I constantly feel this sensation of the vagina opening up or something moving outward. I even underwent a vaginal swab test, and the results came back normal. Please, can someone tell me what condition this might be?
